How do you use the 'Partial<T>' utility type in TypeScript?

Description : 'Partial<T>' makes all properties of a type optional.

Answer :

'Partial<T>' is a utility type in TypeScript that makes all properties of a type 'T' optional. For example, 'type User = { name: string; age: number; }; type PartialUser = Partial<User>;' results in 'PartialUser' having optional 'name' and 'age' properties. This utility type is useful for scenarios where you need to create objects with partial information or update objects with only a subset of properties.

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.
