UPDATE: Recently a brilliant article from Mozilla came up. Read it if you’re curious.
As you may know they are planning to include new Symbol primitive type in ECMAScript 6 (not to mention some other crazy stuff). I always thought that the :symbol notion in Ruby is needless; we could easily use plain strings instead, like we do in JavaScript. And now they decide to complicate things in JS with that.
I don’t understand the motivation. Could someone explain to me whether we really need symbols in JavaScript?
