Length

Arrays have a property called length, and it’s pretty much exactly as it sounds, it’s the length of the array.

  1. var array = [1 , 2, 3];
  3. // Result: l = 3
  4. var l = array.length;

{% exercise %}
Define the variable a to be the number value of the length of the array

var array = [1, 1, 2, 3, 5, 8];
var l = array.length;
var a =
{% solution %}
var array = [1, 1, 2, 3, 5, 8];
var l = array.length;
var a = 6;
{% validation %}
