How can you use 'Record<K, T>' to create an object type?

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 creates an object type with properties where the keys are of type 'K' and the values are of type 'T'. For example, 'type PageInfo = Record<string, number>;' defines an object type with string keys and number values. This utility type is useful for creating objects with a fixed value type but varying 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.
