We’ve been working on #1291 for a while to see how we could add support for ECMAScript 6 and JSX into ESLint. While we were investigating adding ES6 support, we were also getting a fair amount of requests to add JSX support. We soon realized that Facebook’s Esprima fork that supports both ES6 and JSX would be the easiest way to move forward. This left us with some questions about how to support ES
Thanks to two awesome people (Nick and Andy), for introducing me to Esprima. If you have never heard about Esprima, here is a quick intro. Esprima is a high performance, standard-compliant ECMAScript parser written in ECMAScript In simple words, Esprima is a Javascript parser.

The first documented version of HTTP was released in 1995* and has been the backbone of the internet as we know it. But isn't it time for an update? HTTP/2 is an upcoming revision of the age old Internet standard. It keeps almost all the semantics we know and are familiar with from HTTP/1.1 but adds new features that improve performance both in latency and byte efficiency. Many of its features ar
