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...

I wonder if there is a nice way to get the descriptions of a Symbol.  For example,  var s = Symbol(5);   The default implementation of the toString will simply print      Symbol(5)  I would like to find a way to extract the actual description i.e. 5...

Where can I find the list of symbols made available to us by d3.js  which is referred by this line of code:   d3.svg.symbol().type(/*Name of the symbol type that is available to us to use*/'triangle')   Some of the available symbols include t...

I am reading You Don't Know JS: ES6 & Beyond and I encountered this snippet in Symbol.species section.    class Cool {     // defer `@@species` to derived constructor     static get [Symbol.species]() { return this; }      again() {         r...

I am trying to remove special characters from a piece of text, but using the following regular expression  var desired = stringToReplace.replace(/[^\w\s]/gi, '')   (found here: javascript regexp remove all special characters)  has the negativ...

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....
