What is TypeScript and how it works?
TypeScript works by adding enhanced syntax to JavaScript and then transforming it to JavaScript after the TypeScript compiler does its own checks. It doesn’t change JavaScript’s type system. Instead, it adds more checks to it.
Which transpiler is used in Angular?
TypeScript is a primary language for Angular application development. It is a superset of JavaScript with design-time support for type safety and tooling. Browsers can’t execute TypeScript directly.
What is TypeScript vs Angular?
