Mark Zuckerberg and Facebook often try to assist and provide tools for coders, both current and future ones. With that in mind, the social network today announced Hack, an open-source language for programmers. This new language has been used internally at Facebook for the past year and offers a lot of potential for developers, enabling them to program faster and be able to catch errors more easily, among other things. Hack, which was developed for the HHVM platform, is designed to be extremely friendly with PHP; as Facebook puts it, its new programming language "offers the best of both dynamically typed and statically typed languages, and that it will be valuable to projects of all sizes." Essentially, this means you theoretically could have access to websites that are faster and more reliable. Interested in learning more?
