Future Of Java Script
With ECMAScript 6, JavaScript is getting a ton of new features targeted towards making life easier for people building transpilers, i.e. languages that compile down to JavaScript, like CoffeeScript and C++. With asm.js and WebGL, it's actually now possible to run real games that run in the browser without plugins - Brendan Eich has done some very impressive demos with Unreal Tournament running in the browser without plugins. It's slowly but surely becoming the Assembler of the web.

JavaScript is even bringing functional programming to the mainstream. JavaScript programmers are using monads on a daily basis without knowing it. The little functional reactive programming library Bacon.js alone has more stars on GitHub than the Haskell compiler has. This is tremendously important, because with CPUs now nearing the theoretical speed limit per core, multi-core is the way forward, which will drive the industry towards functional programming which eases the complexity of concurrent programming quite a bit.

No matter your opinion of JavaScript, it would be hazardous to your career as a programmer not to know it. It's likely that JavaScript will not only maintain, but extend its hold of the software industry during the coming years.

What  is  a Functional Programming
Functional programming has become a really hot topic in the JavaScript world. Just a few years ago, few JavaScript programmers even knew what functional programming is, but every large application codebase I’ve seen in the past 3 years makes heavy use of functional programming ideas.
Functional programming (often abbreviated FP) is the process of building software by composing pure functions, avoiding shared state, mutable data, and side-effects. Functional programming is declarative rather than imperative, and application state flows through pure functions. Contrast with object oriented programming, where application state is usually shared and colocated with methods in objects.
Functional programming is a programming paradigm, meaning that it is a way of thinking about software construction based on some fundamental, defining principles (listed above). Other examples of programming paradigms include object oriented programming and procedural programming.
Functional code tends to be more concise, more predictable, and easier to test than imperative or object oriented code?—?but if you’re unfamiliar with it and the common patterns associated with it, functional code can also seem a lot more dense, and the related literature can be impenetrable to newcomers.
If you start googling functional programming terms, you’re going to quickly hit a brick wall of academic lingo that can be very intimidating for beginners. To say it has a learning curve is a serious understatement. But if you’ve been programming in JavaScript for a while, chances are good that you’ve used a lot of functional programming concepts & utilities in your real software.
