TypeScript vs. C#: LINQ TypeScript TypeScript has no equivalent for the language-integrated-natural-query aspect of LINQ. (hey, isn't that  literally  the whole acronym?)

Name ; However, the  IEnumerable<T>  extension methods, which are at the heart of LINQ, have equivalents in TypeScript (or can be emulated).
