What is the difference between 'interface' and 'type' for defining objects?
Description : 'interface' is extendable, while 'type' is more flexible with unions and intersections.
Answer :
'interface' and 'type' both define object shapes but have distinct differences.'interface' is extendable and can be merged with other interfaces, making it ideal for defining contracts for objects and classes.'type' is more flexible, allowing for unions, intersections, and other complex type definitions. For example,'interface Person { name: string; }' and 'type Person = { name: string; age: number; }' serve similar purposes but with different capabilities.
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.
