An Introduction To TypeScript for JavaScript Developers

TypeScript for JavaScript Developers

To begin at the beginning developers always have a trilemma, in simple terms when you hire developers for JavaScript development they worry about the project management triangle that is quality, speed, and cost. And if you have the experience working as a JavaScript programmer you might be well aware that every client wants to get a working product as soon as possible without any quality issues and bugs, and most importantly at an affordable cost of development.

As increasing development speed and keeping costs low is going to affect the quality of final work undoubtedly, so this is something that can’t be easily achieved. So with these factors, developers are constantly looking out to find the right balance and keep the client happy without cutting any corners.

Overview on JavaScript

JavaScript is a high-level, multi-paradigm language, released back in 1995, that supports event-driven, functional, and imperative programming styles. Along with CSS and HTML, its use is so widespread that it is called the ‘core technology’ of the world wide web. According to a recent study, there are nearly 1.6 billion websites in the world, and JavaScript is used on 95% of them.

 However, despite JavaScript’s success and a multitude of developers using it a younger challenge was about to challenge for its throne.

 JavaScript, Enhanced

Andres Hejlsberg, the creator of TypeScript, in the year 2010 started working on it and in 2012 the first version of TypeScript was released to the public. It was not until 2017 that it seriously attracted the attention of the development community. As JavaScript grew in complexity, it became heavy, resulting in it falling short in many aspects of a good Object-Oriented programming language. This was particularly detrimental for enterprise-level companies, which created a need for an alternative.

TypeScript was created not as a rival but to bridge the gap! In addition, second to Rust, TypeScript is the most loved language. Therefore, it’s not a surprise that more developers are learning TypeScript. Developed by Microsoft (a single vendor) it works as a superset of JavaScript language, which has a single open-source compiler. To make the JavaScript development more efficient, TypeScript helps to catch the mistakes early through a type system.

Note that it uses all the same components as its parent language, which means that TypeScript is accessible to engineers who understand and use JavaScript, too. From libraries, frameworks, and more, when you hire TypScript developers for JavaScript development they will take advantage of all. It can run on any JavaScript-supported environment and like its parent language, it can be used for both the frontend and backend development.

 That said, it has a number of benefits that elevate the language:

  1. Type checker for both the languages

  2. Adds type syntax to JavaScript to support a tighter integration with your editor

  3. Type checks and transforms your code with the official compiler. TypeScript code converts, which runs anywhere JavaScript runs. For instance, in your browser, Node.JS, and in your apps.

  4. Editing experience is co-developed with the compiler. Plus, TypeScript understands JavaScript and theuser interface to give you great tooling without additional code. 

The addition of static typing and delivering tools makes it more readable, easy, and convenient to use.

Adopt TypeScript: Why do Enterprises need to hire developers for JavaScript Development?

Especially, when you are building large-scale web apps with many thousand lines of code that require multiple developers or dedicated resources, the dynamic typing in JavaScript won’t work for you. This simply means that the code will compile even if it has errors, making it far too easy to end up with a messy code that can be hard to debug and maintain. This is where static typing comes to play to detect several common errors. Plus, it helps to eliminate those hard to debug errors related to variable types.

Static checking doesn’t only help spot type errors and errors that won’t work because of the type, it makes it easier for the integrated development environment to find mistakes during the compilation stage. Both incremental and IDE integrations make everything easier to navigate, identify problems, inspect possibilities, and refactor your codebase. Plus, for larger teams writing a lot of code, all the benefits of TypeScript can be a huge productivity boost.

Your developer will make use of all the added features to make it easier to work with async functions and for using different types when you set property and when you retrieve it. So to get all the benefits, the question here is: What to look for in a developer?

First things first, the several years of experience in other programming languages only count when they have solid grounding in JavaScript. Whether you want them to handle simple or a complex enterprise grade development, you would want someone who is capable to help you leverage the best frameworks and build an full-fledge web solution or a high-performing, feature rich web application- they should have done it all!
