Benefits of TypeScript Over JavaScript TypeScript supports static typing. This means that static typing allows type accuracy to be checked at build time. At the time of development, TypeScript identifies the compilation bugs. As a result, the scope of evaluating errors at runtime is very less. JavaScript, on the other hand, is an interpreted language. TypeScript is just JS with some extra functionality, namely ES6 features. The TS compiler can compile .ts files into ECMAScript, albeit it may not be kept in your chosen web browser. https://mobisoftinfotech.com/resources/blog/typescript-vs-javascript/
