TypeScript vs JavaScript: Which One is Best for Business?

JavaScript is no longer the only programming language used to implement web applications successfully. The market is currently flooded with options, which is improving the state of software development. TypeScript is one of the JavaScript alternatives. It is an improved form of JavaScript that works best for complex applications.

Our article today on "TypeScript vs. JavaScript" will provide you with a thorough understanding of the fundamentals of both technologies, as well as their main points of differentiation, advantages, and other information that will help you decide which one is ideal for your company's needs. So let's start right now.

What is JavaScript?

JavaScript, sometimes known as JS, is a client-side programming language that adheres to the ECMAScript specification. In order to produce dynamic web pages, web/mobile apps, and other digital goods and services, Netscape created one of the fundamental technologies of the World Wide Web. By working with the correct Node JS programmers or a development team, you may employ JavaScript for your server-side operations in addition to client-side scripting. The system embeds programs within HTML pages and analyzes them at runtime.

What is TypeScript?

A superset of JavaScript called TypeScript, or TS, has optional typing. Microsoft created and maintained it as an open-source, object-oriented programming language to address the shortcomings of JavaScript. The TS compiler must be used to translate TypeScript code into its equivalent JavaScript code before the code may be executed. This improves the capabilities of your current JavaScript code and aids in the creation of cutting-edge online and mobile applications that enable efficient client-side and server-side execution.

In a word, TypeScript is a statistically significant typed programming language that enables you to create JavaScript code that is both comprehensible and simple to maintain. It is compatible with Node JS, Deno, and every other browser that supports ECMAScript 3 or later.

TypeScript vs JavaScript: When to Choose?

JavaScript can help you accomplish the following:

  • For observing efficient yet reliable behavior-driven and test-driven development environments, JavaScript may show to be the ideal option.
  • One of the main applications of this technology is modest web projects with fewer teams.
  • JavaScript can be quite useful when you want to create web or mobile applications without needing any build tools.
  • By using JavaScript libraries and frameworks that meet your needs, you may accelerate your development process and produce web apps more quickly.

The following conditions are ideal for TypeScript:

  • Developers may effectively optimise, implement, and run compile-time error checking or validation and run-time type verification thanks to TypeScript.
  • TypeScript is the best option to look out for if you have a complicated project with a lot of code in place and a big development team working together. When talking with API, its interface and access modifiers provide you with a distinct advantage.
  • It is simple to deal with new libraries and frameworks while using TypeScript. For example, you can use IntelliSense to find and browse novel interfaces if your project calls for utilising React and its APIs (both of which include type definitions).

Difference Between TypeScript and JavaScript

Type Definition

In contrast to JavaScript, which cannot determine the type of a variable until the program has run, TypeScript does not allow the use of undeclared variables. JavaScript is an interpreted language, which makes it challenging to spot any bugs and malfunctions while developing. In contrast, TypeScript, a strictly typed programming language, provides mistake detection and correction prior to or during compilation.


The syntax of TypeScript is comparable to that of Java and C#. It shares the same sense of object orientation as these enterprise programming languages.

Learning Curve

A solid understanding of JavaScript's foundational concepts and associated functionalities are necessary to write TypeScript code. It's also essential to have a solid understanding of the OOPs idea. JavaScript, on the other hand, is a scripting language that is simple to master.

Development Community

The TypeScript community is vibrant and welcoming. However, it still isn't developed enough to offer thorough documentation and tools to address each triggering issue. The JavaScript community is substantially bigger and more developed than TypeScript. It is supported by extensive libraries, documentation, and coding standards that assist developers in meeting user expectations.

Number of Developers

There are sufficient JavaScript programmers to meet the market's and users' shifting needs. Depending on the demands of your project, you can select JavaScript expertise. However, even though the number of TypeScript developers is always increasing, finding the proper ones to work with is a very difficult issue.

Which is faster TypeScript or JavaScript?

Despite its widespread use, JavaScript is the slowest language and takes the longest to execute commands. However, both in terms of execution speed and device scalability, Typescript is far faster and more effective than JavaScript.


With the whole TypeScript vs. JavaScript comparison, it is clear that each language has its own advantages and disadvantages. While JavaScript can be used to produce functioning prototypes more quickly, TypeScript assists developers in writing code that is easily understandable and maintained. In 2022, using TypeScript will make more sense when you have the time and a little extra money to hunt for developers with more experience.
