We have learned about arrays in previous lessons. In those lessons, we learned how to perform mathematical operations on data in an array and present them in a table. In this lesson, we will learn how to sort those data and present them in ascending order.
For example, we have a group of students who took computer programming test recently and obtain the marks as shown in the table 24.1. Now, we can sort the mark in ascending order.
|Name of Student||Mark|
Sort is actually the method of an Array object. Therefore, we can initiate the sort method for the Mark using Mark.sort( compareValues ) where compareValues is the comparator function. This function is passed to the sort method as an argument.
The sorted mark show is 12 18 29 33 42 54 60 77 85 100 in ascending order.
