Facebook engineers Bryan O’Sullivan, Julien Verlaguet, and Alok Menghrajani claim they have created a new language that fixes many of the flaws in PHP.
The new language is called Hack, and it already drives almost all of the company’s website — a site that serves more than 1.2 billion people across the globe.
They say Hack is designed to enable software developers to program interactive web pages faster and more effectively by avoiding system-crashing errors. Facebook is releasing it as an open-source language, not just to encourage widespread use but to quickly spot errors in Hack itself, and to build upon the language to give it more strength and features.
Facebook has made PHP (which has had problems like memory leaks, incosistent interfaces, no unicode support etc.) better so it is more like JAVA and other statically typed languages. Because it is compatible with PHP, but adds static typing and other language features, they say it makes the life of developers easier.
While it certainly might make their life easier, if they truely wanted to make a developer's life easier, why not build a low-cost PaaS solultion? Then the developer would not need to code a whole web solution from ground up.
