The document provides an overview of JavaScript and JSON, explaining that JSON is a format for sharing data that is derived from JavaScript and is used to transfer data between a server and browser. It describes the basic syntax of JSON, including that it uses name-value pairs separated by commas within curly brackets for objects and square brackets for arrays, and supports strings, numbers, booleans, arrays, objects and null as data types. Examples are given to illustrate JSON syntax and how it can be parsed in JavaScript to convert it into a JavaScript object.
This document summarizes Max De Marzi's presentation on ETL (extract, transform, load) processes for loading data into Neo4j. It discusses using the Neo4j REST API, Gremlin and Groovy, and the Neo4j Batch Importer for ETL. It also provides an example of ETL from a SQL database by identifying relationships between rows and importing the data without node IDs.
The document discusses the Document Object Model (DOM), which defines a standard for accessing and manipulating HTML and XML documents. It allows programming interfaces to dynamically access and update the content and structure of documents. The DOM represents the page as nodes and objects. It describes the DOM tree structure with parent-child relationships, and methods for accessing nodes by name, ID, tag name, or relative positioning. Examples are given for adding a new text node to the DOM tree. Advantages are robust APIs and easy data modification. Disadvantages include storing the entire document in memory.
The document describes the DOM tree and how it represents an HTML document. It contains three types of DOM nodes - element nodes for HTML tags, text nodes for text content, and attribute nodes for attribute values. It provides examples of traversing the DOM tree using properties like parentNode, childNodes and methods like getElementById. It also discusses how to dynamically add and remove nodes from the DOM using JavaScript methods like createElement, appendChild, setAttribute, and remove.

The document provides an overview of a presentation given by Stephan Schmidt on connecting PHP and JavaScript using JSON-RPC. Some key points:
- It discusses the classic web application model and how business logic resides solely on the server
- With Web 2.0, presentation logic moved to the client but business logic still resides on the server
- The remote proxy pattern can be used to expose server-side business logic as JavaScript objects, making remote calls transparent to the client
- This is done by serializing calls to JSON and making HTTP requests to a JSON-RPC server implemented in PHP
- The server uses reflection to dynamically call the relevant PHP methods and return responses also serialized to JSON

JSON is a lightweight data format that stores and transports data in a text format that is easy for humans to read and write and for machines to parse and generate. It supports strings, numbers, Booleans, arrays and objects. JSON is useful for JavaScript applications like websites and single page apps because it allows asynchronous loading of data faster than XML. JSON is supported across many programming languages and platforms. Common JSON data types include strings, numbers, Booleans, null, arrays and objects. Several online tools can be used to view and edit JSON.

JSON beautifier
JSON beutifier is an online tool. it will help to edit JSON formatter online. JSON is used to represent structured data, such as objects, arrays, numbers, strings, booleans, and null values. It provides a way to organize and store data in a format that can be easily understood by both humans and machines.
JSON is not tied to any specific programming language, making it a universal data format that can be used in various programming environments. JSON uses a simple and readable text format, which makes it easy for developers to create and edit JSON data by hand, and it's also easy for humans to interpret.
JSON is commonly used for data exchange between a client (e.g., a web browser) and a server. When you make an API request to a web service, the response is often returned in JSON format. JSON is used in configuration files for software applications. Many configuration files, like those for web servers, databases, and other software, are written in JSON.
Unlike JavaScript, which can execute code, JSON is a data format and does not execute any code. This makes it safe for handling untrusted data, such as data obtained from user input.
JSON code is a text-based format for representing structured data. JSON code consists of key-value pairs, where keys are strings, and values can be strings, numbers, objects, arrays, booleans, or null. Here's an example of JSON code:
The JSON data is enclosed in curly braces {}.
It contains several key-value pairs, separated by colons :. For example, "name": "John Doe" and "age": 30.
Strings are enclosed in double quotes, like "name", and "John Doe".
Numbers do not have quotes, like 30.
Booleans are represented as true or false.
Arrays are enclosed in square brackets [] and can contain multiple values, like "hobbies": ["reading", "hiking", "coding"].
Objects are nested JSON structures enclosed in curly braces, like "address": { ... }.
{
"name": "John Doe",
"age": 30,
"city": "New York"
}
we have an object with three key-value pairs: "name," "age," and "city." The keys are strings, and the values can be strings, numbers, booleans, null, arrays, or nested objects. JSON is a popular data format for APIs (Application Programming Interfaces) and is supported by many programming languages.
JSON data is represented as a collection of key-value pairs, where the keys are strings, and the values can be various data types such as numbers, strings, booleans, arrays, and other objects. Here's a simple JSON example:
{
"name": "John Doe",
"age": 30,
"isStudent": false,
"hobbies": ["reading", "hiking", "coding"],
"address": {
"street": "123 Main St",
"city": "Anytown"
}
}
JSON is a widely used data format because it's simple, human-readable, and supported by many programming languages. It's commonly used for configuration files, data storage, and exchanging data between a client and a server in web applications.

Dealing with JSON files in python with illustrationsKiran Kumaraswamy
This document discusses JSON files and how to read them into Python using the Pandas library. It first introduces JSON files and their flexible schema that allows for easy human readability. It then explains how to read a JSON file string into a Python dictionary using the json library and the loads() function. It also covers using json.load() to read a JSON file directly and access the values like a standard Python dictionary.
The document discusses JSON (JavaScript Object Notation), which is a lightweight data format that is easy for both humans and machines to read and write. It uses conventions familiar to programmers and is built upon two basic structures: 1) a collection of name/value pairs (objects) and 2) an ordered list of values (arrays). The document then provides more details on the syntax for objects, arrays, strings, numbers, and how these JSON elements can be nested.
This document provides an overview of JSON (JavaScript Object Notation) including what it is, why it is used, its syntax, examples comparing it to XML, where it can be used, and how to use it in JavaScript. JSON is a lightweight data format that is easy for humans to read and write and easy for machines to parse and generate. It is often used to transmit data between a server and web application.
JSON (JavaScript Object Notation) is an open standard format for storing and transporting data. It is language independent and uses human-readable text to transmit data objects consisting of attribute-value pairs and arrays. JSON is lightweight, self-describing and easy to understand. It is derived from JavaScript and uses {} curly braces for objects and [] square brackets for arrays.
This document provides an introduction to JSON (JavaScript Object Notation). It defines JSON as a text format for storing and transporting data that is easy for humans to read and for machines to parse. The document explains that JSON can represent arbitrary data, can be processed by most programming languages, and is useful for transferring data between computers which may interpret data differently.

All about XML, JSON and related topics..tinumanueltmt
JSON stands for JavaScript Object Notation. It was created to hold structured data that could be used in JavaScript but became popular for sending data in web APIs. JSON supports basic data types like strings, numbers, Booleans, and null. XML stands for Extensible Markup Language and is used for structured data like HTML is for websites. Both JSON and XML allow hierarchical data and can be used for data interchange. Key differences include JSON being derived from JavaScript, having a smaller file size, and not containing tags like XML.
This document discusses schema design and CRUD operations in MongoDB. It compares MongoDB and MySQL, and covers how to create databases and collections in MongoDB. It then describes various CRUD operations like create, read, update and delete. Finally, it discusses schema design considerations like one-to-one, one-to-many and many-to-many relationships, and recommends denormalizing data for better read performance.
This document provides an overview of MongoDB, including what NoSQL is, different NoSQL database types like document databases, features of MongoDB like its document-based and schemaless structure, when MongoDB would be a good fit like for large datasets with changing schemas, and how to install MongoDB on Windows, Mac, and Ubuntu.
This document discusses Express middleware and routing. It covers passing data to the server via query parameters, route parameters, and request body. It also discusses creating APIs to handle CRUD operations, using the Request package to make HTTP calls, generating Express applications using Express generator, and using different types of middleware like application-level, router-level, error handling, built-in, and third-party middleware. The document ends with an exercise to build an API to track statistics on requests to routes.
This document provides an introduction to Express, a lightweight web application framework for Node.js. It discusses what Express is, alternatives to Express, and provides an example "Hello World" Express app. It also covers how to create routers in Express to handle requests and routes, and provides an exercise to create an app with three routes. Finally, it mentions making the routers modular by exposing them in separate modules.
- Restful webservices are services that follow the REST architectural style, using HTTP methods like GET, POST, PUT, PATCH, and DELETE to operate on resources identified by URIs. Resources are data entities and representations that are manipulated via their URIs and representations. A restful API should expose resources and operations on them through URI endpoints and HTTP methods instead of exposing methods directly. This document discusses the history of REST, defines key REST concepts like resources and URIs, and provides examples of how to design RESTful APIs and endpoints for resources and collections of resources.
The document outlines JavaScript style guidelines from Airbnb and other sources. It recommends using const and let instead of var, object literal syntax for object creation, array spreads to copy arrays, named function expressions over declarations, arrow functions for anonymous functions, and === over == for comparisons. Comments should use /** */ for multi-line or // for single line and variables should be declared with const and in one line each.

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...DharmaBanothu
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs
3. What is JSON? Why JSON?
- What is JSON?
- JSON stands for JavaScript Object Notation
- JSON is a lightweight data-interchange format
- JSON is "self-describing" and easy to understand
- JSON is language independent
- Why JSON?
- Since the JSON format is text only, it can easily be sent to and from a server, and used as a
data format by any programming language.
4. JSON Syntax
- Data is in name/value pairs
- Data is separated by commas
- Curly braces hold objects
- Square brackets hold arrays
- Name: can be single word, dashed words, underscore words, or
dotted words.
- {"age": 44,"age_i":55, "age.p":100};
