Conditional types in TypeScript allow you to create types based on conditions. Here’s an example:
type IsString<T> = T extends string ? true : false
const test1: IsString<string> = true // Validconst test2: IsString<number> = false // Valid
Conditional types are particularly useful for creating flexible and reusable type definitions.
