Why is TypeScript popular?

TypeScript is a modern programming language loved by engineers for making web development a lot easier. … You can use TypeScript everywhere instead of JavaScript, as it compiles to regular JS code. That’s another reason for its fast-growing popularity.

TypeScript is a superset of JavaScript which primarily provides optional static typing, classes and interfaces. One of the big benefits is to enable IDEs to provide a richer environment for spotting common errors as you type the code.

Why we should use TypeScript?

Easier code refactor – refactoring code in IDE is much easier in Typescript – it works way better than in vanilla Javascript. Sometimes a “wrongly“ named variable in JS can break your refactoring. With Typescript it’s easier for the code editor to find particular, connected variables, functions, classes etc.

TypeScript is definitely the more widely used language that’s transpiled to JavaScript. TypeScript has more support than Flow does with libraries, frameworks, and it’s used more pervasively in apps because of that. They both provide very similar type checking abilities which retain the flexibility of JavaScript.

In contrast to JavaScript, TypeScript code is more reliable and easier to refactor. This enables developers to evade errors and do rewrites much easier.

Is TypeScript type safe?

Back to the question about safety, yes TypeScript ensure safety during writing the code. You define the contract, write transformations of the contract, and TS is checking correctness of the code with relation to contract annotations.

Is TypeScript faster than flow?
