  • Creating and working with Arrays in JS
    Creating and working with Arrays in JS There are several ways to create arrays in Javascript. Also, adding new index values will update the number of items in the array.  Length can be set to update the number of items in the array.  To loop through the items in an array you can use for loop, although this will also return the values that are empty, or you can use forEach which only returns values that are set regardless of the number of blank items in the array.
  • Randomize Array values in place with sort() method in JavaScript
    Randomize Array values in place with sort() method in JavaScript Use the sort method in JavaScript, notice the difference in values using a positive one and a negative one value in the return of the anonymous function within the sort parameters.  If you use Math random to return randomly a negative or positive value this will randomize the array items in place using the sort method.
