They named it Angular 2, removing the JS suffix. They created a new version of AngularJS in TypeScript (which is not backward compatible) and released Angular 2 as a framework in 2016. A few years later, Google engineers completely rewrote the framework to match the needs of today's rich client-side applications.Different versions of Angular JS were released like 1.1, 1.2, and so on. It became popular very quickly because of its feature set. Angular JS was released in 2010 by Google.So what is the deal with all of these version numbers? What is Angular JS, Angular 2, and Angular 4? You really need that faster performance.When developers are already experienced with languages such as C++ and Java and don't want to deal with just JavaScript. Your developers come from strongly typed languages.

When more than one person works on a project and the code base is huge, TS will help you avoid common errors. The most notable of these are classes, interfaces, and compile-time type checks. TypeScript brings several new features to the table. This means that you can easily convert JavaScript to TypeScript later if you need to. If TypeScript is Windows, JavaScript is Linux.Īs was already said, TypeScript is a superset of JavaScript. You have to remember that the main purpose of a type system is to make it hard to break stuff. But it also makes it easier to break things. The lack of a type system makes for agility and ease of changing stuff. However, it's quicker to set up something in JavaScript. TypeScript can actually report issues without you even saving your file, and leverage the type system to help you write code even faster (which leads to a truly awesome editing experience). Using TypeScript can help avoid painful bugs people commonly run into when writing JavaScript by type-checking your code. You can even set the JS version that you want your resulting code on. Also, you can use the other add-ons to the language, and the code will be valid JavaScript. They are supersets of it, which means that every JS code you write is valid TypeScript code. TypeScript does something similar to what LESS or SASS does for CSS. TS has gained a lot of popularity since the Angular 2 project decided to adopt it. Also, check out some other publications we've written, like Introduction to TypeScript or Converting Enterprise Applications to TypeScript.
It is a strict syntactical superset of JavaScript and adds optional static typing to the language.

TypeScript is a free and open-source programming language developed and maintained by Microsoft. Part 1: Introduction to TypeScript What Is TS? And, lastly, we'll go through a tangible TypeScript example for a look into syntax and structure. React, with an eye for what you need to know to understand the JavaScript tooling landscape TypeScript plays in. We will then discuss the differences between the different versions of Angular, and Angular vs. To do so, we will first give an introduction to TypeScript. The goal of this post is to provide you with an understanding of TypeScript, particularly when you come from an AngularJS web development background. I want to make that transition easier for you! When I ended up coming face-to-face with TypeScript, it felt new, scary, and pretty confusing. Angular, jQuery, and traditional JavaScript have been in my comfort zone. My web development experience over the last few years has mainly included the AngularJS and Backbone.js frameworks. This generates a dilemma: which solution should we use when starting a project? New JavaScript frameworks and libraries are created every day.
