Sorting numbers. We use built-in functions of javascript to sort the values ascending in an array.
Here, we create an array called “numbers” with values.
var numbers =["4","7","9","1"];we use .sort() function to sort it. Before .sort() you should be adding the array variable. In this case,
numbers.sort()This will sort the items in ascending order. To sort descending,
numbers.sort();
numbers.reverse();<html>

/*  This command is sort the fruits name in alaphabetic order */
/* you can use numbers.revese(); function to order the values in descending order */
