Escapes single quotes, `"`, `<`, `>`, `&`, and fixes line endings.

Escapes text strings for echoing in JS. It is intended to be used for inline JS (in a tag attribute, for example onclick="..."). Note that the strings have to be in single quotes. The {@see 'js_escape'} filter is also applied here.
