Difference between grep and map in jquery

Grep and Map

     The $.grep() and $.map() are two array utilities provided by jQuery to filter an array. The main difference is that grep() method filters an array and returns the filtered array, while map() simple applies a function to each item in the array, thus returning a modified array. The following is the format and example of grep() and map().

$.grep()

$.grep (array, function (value,index) {

 ------

 ------

});

     The first parameter is the array we want to filter. The second parameter is the numerical index of each array’s item. The third parameter is the actual value of each item in array.

$.map()

$.map (array, function (value, index) {
 ------
 ------
});

     The first parameter is the array we want to apply a function on its items. The second parameter is the actual value of each item in array and the third parameter is the numeric index of each item.
