Question

var a = [432, 238, 122, 883, 983];

And I want to limit t

Answer 1

You can also use Array.pop. Also if you wish to add a property to array, you can make it generic.

Array.prototype.Limit_push = function(x) {
  this.unshift(x);
  if (this.maxLength !== undefined && this.length > this.maxLength) 
    this.pop();
}

var a = [];
a.maxLength = 7
for (var i = 0; i < 10; i++) {
  a.Limit_push(i);
  console.log(a)
}

var b = [];
for (var i = 0; i < 10; i++) {
  b.Limit_push(i);
  console.log(b)
}
