The arr.push() method is used to push one or more values into the array. This method changes the length of the array by the number of elements added to the array.

Syntax:

arr.push(element1, elements2 ....., elementN]])

Parameters This method contains as many numbers of parameters as the number of elements to be inserted into the array.

Return value: This method returns the new length of the array after inserting the arguments into the array.



Below examples illustrate the JavaScript Array push() method:

  • Example 1: In this example the function push() adds the numbers to the end of the array.
    var arr = [34, 234, 567, 4];
    print(arr.push(23,45,56));
    print(arr);
    

    Output:

    7
    34,234,567,4,23,45,56
    
  • Example 2: In this example the function push() adds the objects to the end of the array.
     
    var arr = [34, 234, 567, 4];
    print(arr.push('jacob',true,23.45));
    print(arr);
    

    Output:

    7
    34,234,567,4,jacob,true,23.45
