Primitive Data Types, Arrays, Loops, and Conditions

Summary

In this chapter, you learned a lot about the basic building blocks of a JavaScript program. Now you know the primitive data types:

number
string
boolean
undefined
null

You also know quite a few operators:

Arithmetic operators: +, -, *, /, and %.
Increment operators: ++ and --.
Assignment operators: =, +=, -=, *=, /=, and %=.
Special operators: typeof and delete.
Logical operators: &&, ||, and !.
Comparison operators: ==, ===, !=, !==, <, >, >=, and <=.

Then you learned how to use arrays to store and access data, and finally you saw different ways to control the flow of your program—using conditions (if-else or switch) and loops (while, do-while, for, for-in).

This is quite a bit of information and it is recommended that you now go through the exercises below, then give yourself a well-deserved pat on the back before diving into the next chapter. More fun is coming up!
