In the long run, I think we'll find that it's easier to read, simpler to write, and less error prone where inheritance is concerned. All of the previous syntax is legal, though, right, so it's up to you and your needs. I'm just starting with it, but that's the impression I've gotten.

The syntax itself is the difference. People already familiar with other languages often find the new syntax easier to use than the traditional prototypical syntax of JavaScript.

On the other hand, I saw a video lecture by famous JavaScript scholar Douglas Crockford where here said he still prefers to use the traditional syntax because it more accurately reflects what's happening "under the hood".
