Sorting Javascript Array with Chrome?

The comparer function should return a negative number, positive number, or zero (which is a convention across programming languages).

myArray.sort(function(a, b) {  return a-b;});

The behavior of Chrome is correct :)

The ECMA standards require the function being passed to sort() to return a number greater than 0, less than 0 or equal to 0. However, the function you have defined returns true / false. ECMA standards state that for a function which does not behave as expected, the implementation depends on the client.

Because of what the ECMA Standard covers about sort arrays (in a very simplified way):

• If in the comparison receives 1 A descend one position.
• If receives -1 maintain the position and define the superior rankingtoward the B.
• If receives 0 does nothing.

The safest way to guarantee the same behavior in all browser is :

// descending orderabc =[10,2,4,1]; abc.sort(function( a , b ){  return a > b ? -1 : 1;});// ascending orderabc.sort(function( a , b ){  return a > b ? 1 : -1;});

For primitive objects is posible to use the short version

// descending orderabc.sort(function( a , b ){  return b - a; });// ascending orderabc.sort(function( a , b ){  return a - b; });

if you have next array:

var items = [       { name: 'Edward', value: 21 },       { name: 'Sharpe', value: 27 },       { name: 'And', value: 31 },       { name: 'The', value: -12 },       { name: 'Zeros', value: 37 },       { name: 'Magnetic', value: 37 } ]

The right way is:

 items.sort(function( a , b ){   var result = a == b ? 0 : b > a ? -1 : 1   if(result === 0)   {     // implement a tight break evaluation   }   return result ;  });

This is the right way because the way that the browser iterates is not defined in the ECMA standard and browser may iterate in different ways. For instance most browsers iterate from top to bottom, but chrome iterates the 1st element with the last and go the way up. So in case of a tight may result different result of most browsers.
