How to append something to an array?

Answer 1

Let the array length property do the work:

myarray[myarray.length] = 'new element value added to the end of the array';

myarray.length returns the number of strings in the array. JS is zero based so the next element key of the array will be the current length of the array. EX:

var myarray = [0, 1, 2, 3],
    myarrayLength = myarray.length; //myarrayLength is set to 4
