Typescript used in Web Development Typescript is a super set of Javascript. It validates your Javascript ahead of time with static type checking.

Why typscript ?

  • Code is interpreted by the browser but if the code is broken then it gives runtime errors (usually when you right click and check for console.log errors in old websites)
  • Typescript prevents this by extending Javascript with types. Where an IDE like vscode provides feedback.
  • It behaves like a compiler.
    let appName : String   //explicit
    let appName ="string"  //implicit
    let appName=any="string" //loosely typed
