has.js | Pure Feature Detection Library | Web Framework library

has.js is a JavaScript library typically used in Server, Web Framework, Symfony applications. has.js has no vulnerabilities and it has medium support. However has.js has 4 bugs. You can download it from GitHub.

Browser sniffing and feature inference are flawed techniques for detecting browser support in client side JavaScript. The goal of has.js is to provide a collection of self-contained tests and unified framework around using pure feature detection for whatever library consumes it. You likely won't see has.js as a public API in any library. The idea is that %yourfavoritelibrary% will import some or all the available tests, based on their own needs for providing you a normalized future proof API against common tasks. not stable, so keep that in mind. This is a young project, and the decided naming conventions may be a moving target. The tests are nothing that haven't been done over and over in various places, so the intention is to come to some agreement on a basic naming convention and API based on real world use cases.
