JavaScript keeps on expanding. As adoption of extensive new features has spread and projects have adapted over the last few years, the language has continued to evolve under the guidance of Ecma TC39. Over the past three years, beyond ES6, another handful of constructs entered the ECMAScript specification. And there are nearly two dozen more proposals on the cusp of being added.

One thing is certain: the JavaScript community is not slowing down! How can we determine when it is “safe” to use a new feature? Investigate the new and proposed features of JavaScript. Understand the TC39 review process. And most of all, become empowered to prepare for what lies ahead.
