Summary


We now have an idea of why a developer would choose to use a JavaScript framework rather than writing all code from scratch, even for the most basic tasks. We also have seen some of the ways in which jQuery excels as a framework, and why we might choose it over other options. We also know in general which tasks jQuery makes easier.

In this chapter, we have learned how to make jQuery available to JavaScript code on our web page, use the $() factory function to locate a part of the page that has a given class, call .addClass() to apply additional styling to this part of the page, and invoke $(document).ready() to cause this code to execute upon the loading of the page.

The simple example we have been using demonstrates how jQuery works, but is not very useful in real-world situations. In the next chapter, we will expand on the code hereby exploring jQuery’s sophisticated selector language, finding practical uses for this technique.
