How do you use the 'Record<K, T>' utility type in TypeScript?
Description : 'Record<K, T>' creates an object type with keys of type 'K' and values of type 'T'.
Answer :
'Record<K, T>' is a utility type in TypeScript that constructs an object type with keys of type 'K' and values of type 'T'. For example,'type PageInfo = Record<string, string>;' creates a type where each property is a string key with string values. This is useful for creating objects with a known value type but dynamic keys.
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.
