Difference between a map and reach function.
| $.map | $.each |
| map method can be used as an iterator | each method is an immutable iterator |
| Return a New array | Return an original array |
| Does not have a way to terminate the iteration | Return false to terminate the iteration |
Example:
$(document).ready(function () {
var intArray = [1,2,3,4,5];
function functionA( index, element ) {
return element * 5;
}
function functionB( element, index ) {
return element * 5;
}
var result1 = $.each(intArray , functionA);
var result2 = $.map(intArray , functionB);
document.write('each = ' + result1);
document.write('<br>');
document.write('map = ' + result2);
});
