var array=[1,2,3,4,5];
Console.log (array); [1, 2, 3, 4, 5]
Array.push (6); A parameter
console.log
The pop operation takes the last element of the array out and returns:@array =5..9;$fred =pop (@array); # $fred Get 9, @array now (5,6,7,8)$barney =pop@array; # $barneygets 8, @array now (5,6,7)Pop@array; # @array Now (5,6) (7 is discarded)In the last example, a pop is used in "Inavoidcontext", which means there is no place to store its return value. It is legal to use POPs in this way.If the array is empty, the pop does nothing (because no elements can be moved out) and returns to undef.You may

Both of these "push" implement
