Regardless of this key distinction from JavaScript, TypeScript can nonetheless be executed wherever JavaScript can run. That’s as a result of TypeScript compiles to not a binary executable, however to straightforward JavaScript.
TypeScript vs. JavaScript
TypeScript is a superset of JavaScript. Whereas any right JavaScript code can also be right TypeScript code, TypeScript additionally has language options that aren’t a part of JavaScript. Essentially the most distinguished function distinctive to TypeScript—the one which gave TypeScript its identify—is, as famous, sturdy typing: a TypeScript variable is related to a sort, like a string, quantity, or boolean, that tells the compiler what sort of information it may well maintain. As well as, TypeScript helps sort inference, and features a catch-all any sort, which implies that variables don’t must have their varieties assigned explicitly by the programmer.
TypeScript can also be designed for object-oriented programming, whereas JavaScript just isn’t. Ideas like inheritance and entry management that aren’t intuitive in JavaScript are straightforward to implement in TypeScript. As well as, TypeScript lets you implement interfaces, a largely meaningless idea within the JavaScript world.
