Au contraire, it is essential for it to work. The Array.prototype.sort
method will run this function on two elements and sort them depending
on the returned value. It works the same as the -1:0:1 return values
the alpha sort uses.
As for fixing it, try doing like this, if you want to sort numericals
above and non-numericals below:
function numSort(a,b){
return (isNaN(a)?Number.POSITIVE_INFINITY:a)-(isNaN(b)?Number.POSITIVE_INFINITY:b)
}
If you want to sort the numbers and numerical strings numerically but
the non-numerical strings alphabetically, try this:
function numAlphaSort(a,b){
return (isNaN(a)&&isNaN(b))?
alphaSort(a,b);
numSort(a,b);
