JavaScript vs. TypeScript

by Angie Jacobo

There are so many coding languages, each with its own ups and downs. So between JavaScript and TypeScript, which is better? Well, that depends on who’s asking.

JavaScript

JavaScript is used in web development which makes it simple to update content, animate images, control multimedia, and more.

Pros

JavaScript is probably the most popular language for many reasons. For starters, its prewritten code makes it easier for beginners to learn. Much of it can be self-taught, using the many resources there are online. Along with its simplicity, JavaScript is compatible with many other languages, which is crucial for websites and games coded in other languages. JavaScript is also always updated to include more frameworks and libraries, maintaining its relevance to users.

Cons

Though JavaScript is beginner friendly, it poses some challenges when things go wrong. Debugging, for example, takes longer because the code does not show or notify the user of any errors. Finding the error becomes a tentative process that is unappealing to users. In addition to debugging, browser compatibility poses another challenge for some web browsers because they may interpret JavaScript differently.

TypeScript

TypeScript is derived from JavaScript. Its purpose was to embody the simplicity of JavaScript, but also improve the user experience.

Pros

TypeScript is different from other languages that attempt to become “better” versions of JavaScript. One of the best benefits of using TypeScript is its ability to notify the user of errors and solutions to them. This makes debugging much more efficient and is a feature that JavaScript lacks. Additionally, TypeScript is converted into its JavaScript code equivalent, so if you know JavaScript, you could learn TypeScript. Furthermore, because you can convert TypeScript into JavaScript, it is compatible with many other languages.

Cons

Though it is not completely a con, TypeScript has a more complex typing system than JavaScript. This is because TypeScript is more precise in language, but this can also be a benefit for users seeking specificity that JavaScript lacks. Another con to TypeScript is the long time it takes to compile the code. A compilation is a process of converting a high-level programming language into a machine language that the computer can understand. This process is necessary, so it may be a burden to some users.

Which One Should You Choose?

I recommend trying both and seeing what you like better. Whether or not their pros outweigh their cons is up for debate amongst coders, so there is no one correct answer because it all depends on your needs and preferences. Each language is beginner friendly, perfect for anyone interested in trying them out. Whichever you choose, have fun with it!
