What's wrong with var x = new Array();

Question

In JSLint, it warns that

var x = new Array(); 

(That's not a real variable name) should be

var result = []; 

What is wrong with the 1st syntax? What's the reasoning behind the suggestion?

Answer 1

It's safer to use [] than it is to use new Array(), because you can actually override the value of Array in JavaScript:

Array = function() { };  var x = new Array(); // x is now an Object instead of an Array. 

In other words, [] is unambiguous.

Answer 2

Crockford doesn't like new. Therefore, JSLint expects you to avoid it when possible. And creating a new array object is possible without using new....
