cssesc: CSS String and Identifier Escaping

cssesc is a JavaScript utility library designed for safely escaping arbitrary strings and identifiers for use within CSS. It specializes in producing the shortest possible valid ASCII-only escape sequences, making it efficient for various web development scenarios. Currently at stable version 3.0.0, it offers more granular control than the native `CSS.escape()` method or its polyfills. Key differentiators include the ability to specify if the output is intended for a CSS string literal or a CSS identifier, and control over quote preferences for string wrapping. Its release cadence is typically measured, reflecting its nature as a focused utility library with a stable API. It declares compatibility with Node.js versions 4 and higher, making it widely compatible, though modern usage typically occurs on much newer environments.
