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...
What is the point of the 'Symbol' type in ECMA-262-v6? Fast path implementation for object keys? What does it do under the hood - hash it with the guarantee that the underlying data is immutable?...
I've been around the block when it comes to languages, having worked with everything from C# to Lisp to Scala to Haskell, and in every language that supported them, symbols have acted pretty much the same; that is, any two symbols with the same n...

It only happens with #toString, and only when I (try to) access it through a missingMethod-like trap.  I have a factory called createIterface which returns a Proxy of an object with a large number of methods. Among this methods, I have both #toString...
I'm sure this has been covered in another question on here however, after trying many different examples on my code i cannot seem to get this to work.  I am trying to make the nodes on my force-directed graph a different shape depending on the na...
How can I check if a special character is available in the user's computer?  For example: ? ? ? ? ? ? ¶  If the user's browser doesn't support one of them, then a rectangle (????) will appear instead of the symbol....
