JavaScript or TypeScript? This decision is considered by developers for new web applications, but it is also pertinent for current projects. TypeScript, a superset of JavaScript, provides all the functionality of JavaScript plus additional advantages.
TypeScript pushes us to write clean code, which makes the code more scalable. Using TypeScript is not an all-or-nothing option, as projects can contain as much plain JavaScript as desired.
The computer programming language JavaScript was first designed to be used on the client-side.
As a result of its application in web development, developers found that JavaScript could also be considered a server-side programming language. This was a discovery made by developers.
