We have seen that the use of JavaScript is not required to develop complete applications. However, the WaveMaker client framework provides a rich palette to work with for those who wish to take advantage of JavaScript.

Once we understand events, we will explore some of the things we can do within those events. We will work with wm.Variables and see how they act as instruments for getting and setting data values. Not to be left out, we'll also include the role of JavaScript variables in page code.
