Question

I’m looking for a jQuery method to merge two arrays so that their values alternate:

var array1 = [1,2,3,4,5];
var array2 = ['a', 'b', 'c', 'd', 'e'];

The result I want is:

var arrayCombined = [1, 'a', 2, 'b', 3, 'c', 4, 'd', 5, 'e'];

Please note that I know it is trivial to do this in JS, however I am after a jQuery method that will do this.

Answer 1

You can use the map method:

var array1 = [1, 2, 3, 4, 5];
var array2 = ['a', 'b', 'c', 'd', 'e'];

var arrayCombined = $.map(array1, function(v, i) {
  return [v, array2[i]];
});

console.log(arrayCombined);
