Introduction to TypeScript, demo ( http://goo.gl/VtE4Vm ), Comparison with couple of popular alternatives. (Sadly layout of the slides are a bit ruined by conversion to SlideShare format - original file: http://goo.gl/eeJgbR )
Not so long ago Microsoft announced a new language trageting on front-end developers. Everybody's reaction was like: Why?!! Is it just Microsoft darting back to Google?!
So, why a new language? JavaScript has its bad parts. Mostly you can avoid them or workaraund. You can emulate class-based OOP style, modules, scoping and even run-time typing. But that is doomed to be clumsy. That's not in the language design. Google has pointed out these flaws, provided a new language and failed. Will the story of TypeScript be any different?

Slide 1
TypeScript
* This presentation is to show TypeScript's major feature and the benefit that it brings to your JavaScript projects.
* Our main objective is just to spark interest especially to those not familiar with the tool.
Slide 2
- What is TypeScript
* go to next slide
Slide 3
- Is a superset of JavaScript
* it simply means an extension to JavaScript
- Use JavaScript code on TypeScript
* JS code naturally works on TypeScript
* Which also means your beloved JavaScript libraries such as JQuery, or your fancy interacive plugins would work as well.
- TypeScript compiles to plain old JavaScript
* TS code compiles to simple and clean JS.
Slide 4
- Screenshot of TS compiled to JS
* In this example, compiling a TS class code would result to a JS version, and a regular JavaScript function when compiled is basically untouched.
Slide 5
- TypeScript's Main Feature
* So what does TS provide us with? What does it actually do?
Slide 6
- Static Type Checking
* TypeScript allows us to enable type checking by defining data types to your for ex. variables, function parameters and return types.
Slide 7
- Screenshot of basic Static Type Checking
* In this example…
* What I've done here was to assign supposedly wrong values for what the variables or parameters were meant to hold
* As JavaScript is a dynamic and untyped language these expressions would either fail or be okay when you run it on your browser.
* In TypeScript by enabling static type checking these potential errors are caught earlier (see the red marks on the expressions) and wouldn't even allow you to compile unless these are resolved.
* In addition you can also type arrays and object literals
Slide 8
- Effects of Static Type Checking
* As TS code is statically type-checked a side effect of such...
- Allows IDEs to perform live error checks
- Exposes auto-completion and code hinting
Slide 9
- Screenshot of code hinting
* Say I was coding JQuery on regular JavaScript code there would be no natural way to help me identify its class properties, methods and parameters... except through reading the API documentation or a separate plugin.
* As a result of static type checking this allows IDE's to access these class members as code hints
* So if this was a 3rd party library how much more if you are just referencing your own JavaScript/TypeScript files within your project.
Slide 10
- A few of the other cool features
* That was only the basic feature of TypeScript
* A few of the other cool features are...
Slide 11

What is TypeScript? It's Definition, History And FeaturesHarryParker32
TypeScript is a programming language that is a super set of JavaScript. It was developed and is maintained by Microsoft. TypeScript was first released in 2012 and has since gained popularity as a language for large-scale JavaScript applications.
It adds optional static typing, classes, and interfaces to JavaScript, making it more suitable for building complex and maintainable applications. TypeScript also includes features such as interfaces, decorators, and async/await, which are not present in JavaScript. Additionally, TypeScript has built-in support for JSX, the syntax extension for React, making it a popular choice for React developers. TypeScript code can be transpiled to JavaScript, allowing it to run in any JavaScript environment.

Recently I got a chance to put together a presentation and a demo around TypeScript and SharePoint. This is the presentation for the same...more details can be found on my blog at https://aseempandit.wordpress.com.
This tutorial on typescript with node and express js will walk you through to all the topics like what is typescript, what is node js, what is express js and then we will see how to setup typescript with node and express. TypeScript is an object oriented programming language, It is a strongly typed superset of JavaScript and all the code of typescript is complied with JavaScript, It was developed and maintained by Microsoft and typescript was created to develop large applications.
Node js - Node.js is an open-source, cross-platform JavaScript runtime environment, and it runs on a web application outside the client's browser. Node js is used by the developers to build server-side web applications, it is perfect for data-intensive applications since it uses an asynchronous, event-driven model.
Express js - Express is a node js framework designed to build API's web applications, cross-platform mobile apps quickly and easily. It is Unopinionated, Express JS makes the node js easy and is used as a server-side scripting language.
TypeScript app development service is a valuable option for building large-scale applications, as it provides several features such as static typing, classes, and interfaces that can improve the development process and the quality of the resulting software. It also has a large ecosystem of tools and libraries, and an active community that can help to speed up the development process and reduce the need to write boilerplate code.
Reasons to Use Typescript for Your Next Project Over Javascript.pdfMobMaxime
Do you know that TypeScript is considered a better programming language than JavaScript? Yes, it's true. Wondering Why? We’ll discuss this in complete detail today.
TypeScript starts from the same syntax and semantics that millions of JavaScript developers know today. Use existing JavaScript code, incorporate popular JavaScript libraries, and call TypeScript code from JavaScript.
TypeScript compiles to clean, simple JavaScript code which runs on any browser, in Node.js, or in any JavaScript engine that supports ECMAScript 3 (or newer).

TypeScript and Angular2 (Love at first sight)Igor Talevski
“We love TypeScript for many things… With TypeScript, several of our team members have said things like ‘I now actually understand most of our own code!’ because they can easily traverse it and understand relationships much better. And we’ve found several bugs via TypeScript’s checks. “
– Brad Green, Engineering Director - AngularJS
Making Visualforce RemoteActions Bulletproof with TypeScriptSimon Goodyear
My Dreamforce '15 presentation which discusses how we can use TypeScript in Visualforce. The video is here; http://salesforce.vidyard.com/watch/XT20D_JUgU4jBe5SjHy_Rg
RemoteAction Apex methods have helped make Visualforce pages more responsive by allowing us to use more JavaScript and still connect easily to our Apex business logic. But with this power comes the brittleness of JavaScript's untyped nature and the disconnect between JavaScript and Apex methods. The errors caused by these issues are runtime errors, which can slow development down. To catch these errors at compile time, the Tooling API can be used to generate TypeScript proxies for RemoteActions. Join us to learn what TypeScript is, how to use it in Visualforce, and see concrete examples of how to generate proxies for Apex RemoteActions.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. AGENDA
• Introduction
• Why TypeScript?
• Featured
• TypeScript VS
JavaScript
• Who uses TypeScript?
• Conclusion
3. INTRODUCTION
TypeScript is a scripting language developed and maintained by Microsoft.
It is a strict syntactical superset of JavaScript.
TypeScript is designed for the development of large applications and trans compiles
to JavaScript.
4. WHY TYPE
SCRIPT?
TypeScript simplifies
JavaScript code,
making it easier to
read and debug.
Provide an
optional type
system for
JavaScript.
It has more modular
development.
It has more
planned features
than JavaScript
versions.
TypeScript makes
code easier to read
and understand.
6. TYPE SCRIPT VS JAVA SCRIPT
Typescript is a superset
of JavaScript.
Typescript code needs
to be compiled.
Typescript uses
concepts like types and
interfaces to describe
data being used.
Typescript is a powerful
type system, including
generics & JS features
for large size project.
JavaScript is a
scripting language
which helps you create
interactive web pages.
JavaScript code doesn’t
need to compile.
JavaScript has no
such concept.
JavaScript is an ideal
option for small size
project.
8. CONCLUSION
It is safer and more modular.
It has high value, low-cost improvement
over java script.
To use TS, we need to know to some
quirks of JS.
Current compiler of TS is little slow, the
faster is under development.
