Key Points to Remember

  • All TypeScript statements must end with a semicolon (;).
  • TypeScript is a superset of JavaScript and shares most of its syntax, but it adds static typing and other features for large-scale applications.
  • Comments can be added using // for single-line comments or /* ... */ for multi-line comments, similar to JavaScript.
  • TypeScript is transpiled to JavaScript during compilation, making it compatible with all JavaScript environments.
