Control Flow

Zap provides simple and powerful control flow structures.

While Loops

The while loop repeatedly executes a block of code while a condition is true. Parentheses around the condition are optional.

var i: Int = 0;
while i < 10 {
    i = i + 1;
}

If Expressions

In Zap, if is an expression, meaning it can return a value. This can be used for conditional assignments.

var age: Int = 18;
var status: String = if age >= 18 { "adult" } else { "minor" };

You can also use it as a standard statement:

if age >= 18 {
    // some logic here
} else {
    // some logic here
}
