The escape() function (or unescape) was deprecated in JavaScript version 1.5. Use encodeURI() or encodeURIComponent() instead.

MDN actually lists escape and unescape as valid ESNext functions, FYI. Working on a PR

This behavior is intentional. Please see #8639 (comment).

You can always define:

declare function escape(s:string): string;
declare function unescape(s:string): string;

Have seen #8639 and find nothing about deprecated here.

Copying comment from other thread

@k8w those pages used to refer to it being deprecated, and it was. It does not appear to be deprecated in the current standard though, and I can't find a specific reference to why the change was made. I suspect they were retained in the specification to not break code, but you shouldn't be using them for new code as they don't handle Unicode URIs properly, and so IMO they are best to leave out and people can add them back in if they are supporting old code.
