What is the difference between 'interface' and 'type' in TypeScript?
Description : 'interface' is used for object shapes, while 'type' can define various types.
Answer :
'interface' and 'type' are both used to define types in TypeScript, but they have some differences.'interface' is primarily used to define the shape of objects and can be extended or implemented.'type' is more versatile and can define union, intersection, and other complex types. For example,'interface Person { name: string; }' defines a shape for'Person',while'type ID = string | number;' defines a union type.
TypeScript is a statically typed language that builds on JavaScript by adding optional types. It allows developers to catch errors at compile time rather than runtime, which can help improve code quality and readability. TypeScript code is transpiled to JavaScript, making it compatible with existing JavaScript codebases and environments.
