I have an array of strings like ['2', '10', '11']
and was wondering what's the most efficient way of converting it to an integer array. Should I just loop through all the elements and convert it to an integer or is there a function that does this?

Use map()
and parseInt()
var res = ['2', '10', '11'].map(function(v) {
return parseInt(v, 10);
});
document.write('<pre>' + JSON.stringify(res, null, 3) + '<pre>')
