Meanstack Introduction by Kishore Chandra
This document provides an overview of the MEAN stack, which is a full-stack JavaScript framework that simplifies and accelerates web application development. It defines MEAN as an acronym for the technologies it incorporates: MongoDB for the database, Express for the server framework, AngularJS for the client-side framework, and Node.js for the runtime environment. Each technology is described in 1-2 sentences. The document then discusses advantages like using a single programming language throughout and disadvantages like lack of coding guidelines. It concludes that MEAN provides a fast, easy way to build modern web applications.
Vlad zelinschi optimizing the critical rendering path
The document discusses optimizing the critical rendering path (CRP) of a web page. The CRP refers to the steps between receiving HTML, CSS, and JavaScript and rendering pixels on the screen. These steps include parsing HTML to build the DOM tree, parsing CSS to build the CSSOM tree, combining them into a render tree, running layout to compute geometry, and painting to the screen. Optimizing the CRP means minimizing the time spent in these steps. Some tips include getting CSS to the client fast, eliminating blocking JavaScript from the CRP, and focusing on above-the-fold content. Tools like critical CSS extraction can help optimize the CRP.

FULL stack -> MEAN stack
popular FULL stacks and full reference of an MEAN stack with real time applications and more.MEAN stack is mainly for single page web applications and have an professional dynamic web page.
Node js
Node.js is a JavaScript runtime environment that uses Google Chrome's V8 engine. It allows for high concurrency without threads or processes by using an event loop and callbacks for non-blocking I/O. While it can be used for server-side JavaScript applications, its lack of access to the DOM from the server-side presents some drawbacks compared to traditional client-side JavaScript. Overall, Node.js enables highly scalable applications but its non-blocking nature requires some adjustment for developers accustomed to blocking I/O models.

WebAssembly vs JavaScript: What is faster?
- WebAssembly is a new low-level compilation target that runs at native speed by taking advantage of common hardware capabilities available on a web platform.
- While WebAssembly is very fast for pure computations, calling JavaScript from WebAssembly can lead to slowdowns. Interacting with the DOM or host APIs may also be slower than native code.
- WebAssembly is best suited for applications that require a lot of computation, are developed with a focus on performance, and have minimal interactions with JavaScript or the DOM. This includes porting existing C/C++ libraries and algorithms to the web.
MEAN Stack
The document discusses the MEAN stack, which is a full-stack JavaScript platform for building modern web applications. It is composed of MongoDB (M) as the database, Express.js (E) as the backend framework, AngularJS (A) as the frontend framework, and Node.js (N) as the runtime environment. The document provides descriptions of each component, why the MEAN stack is useful, how to deploy a MEAN application to Heroku cloud, and some tips on getting started and potential limitations.
Using type script to build better apps
TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It allows you to write JavaScript in a more structured way using types, classes, and interfaces. Using TypeScript can help catch errors early and provide better code completion through tooling. While TypeScript adds types and other features, JavaScript code is still valid TypeScript code. The TypeScript compiler outputs plain JavaScript that runs on any browser or environment.

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine that allows for writing server-side code in JavaScript. It has a single-threaded, event-driven architecture that makes it efficient for data-intensive real-time applications. Some key advantages of Node.js include using JavaScript for both client-side and server-side code, high performance due to event-driven and non-blocking model, and rich ecosystem of third-party modules. Mobile web apps can be built with Node.js by using HTML5 features and JavaScript on the server and client sides.
SSJS, NoSQL, GAE and AppengineJS
Server-side JavaScript (SSJS) is gaining popularity due to factors like the rise of NoSQL databases, asynchronous programming, and JavaScript's ubiquity. SSJS environments like Node.js, CommonJS, and AppEngineJS allow developers to use JavaScript beyond the browser by running it on the server. Google App Engine also provides a platform for hosting SSJS applications and automatically scaling them.
