if Statements

As the variable is a foundational data tool in your programs, the if statement is the primary way to manage control flow. The if statement allows you to direct the program flow based off questions. These are not open-ended questions, rather they must resolve to either true or false.

For example, is the user a premium account holder? Is the user over eighteen? Does the user’s post contain over ten comment?

From theses simple questions, you can change the behavior of your program.

Using Boolean Operators

Boolean operators are the key to if statements. These operators compare two values and produce a true or false result. For example:

let falseValue = "Luke" == "Yoda"

Pbo == xnecrg pur asioheyy. On snah haxe, qga chcoqr Yibo read zej ajaok kyu bxmiwf Vela ta bke yebehc us tgos kolmopanos ey qiwwa.

Working with Braces

When you define an if statement, you start with the keyword if followed by the checked condition. You then provide a pair of curly braces. For example:

if age > 21 {
  // code goes here
}
