Javascript Join Array

The string conversions of all array elements are joined into one string. If an element is undefined or null, it is converted to an empty string instead of the string quotnullquot or quotundefinedquot.. The join method is accessed internally by Array.prototype.toString with no arguments. Overriding join of an array instance will override its toString behavior as well.

BadHorsie No, it is not DRY. But of course you could define a single function outside of the array and then assign this function to the toString method of all items, using a for-loop. Or you could use this approach when dealing with constructor functions, by adding one toString method to the prototype property for the constructor. This example however was just supposed to show the basic concept.
