Getting Started,There are a couple of ways you can start using p5.js and JavaScript. One option is to visit the p5.js website (.) and download the p5.js source code on to your system (see Figure .).

Operators and Variables,In Chapters 1 and 2 we learned about variables and math operations that we can use in JavaScript. In this chapter, we will put that knowledge to use.

Conditional Statements and Comparison Operators,In the previous chapter, we saw some of the variables that p5.js makes available for us. One important thing to note is that these variables can only be used from inside the p5.js functions setup and draw. If we were to try to use them outside these functions, we would get an error saying that they are not declared.

More p5.js Variables,In the previous chapter, we learned about the p5.js frameCount variable that provides us with a number that represents the number of times the draw function is called. There are a bunch of other highly useful variables that we could be using in p5.js. We will learn a few more in this chapter.
