Control Flow

Nubo includes straightforward control flow for branching and looping.

If Statements

Use if to run code conditionally:

if x > 1 {
    println("x is greater than 1")
}

Conditions usually use comparison operators such as ==.

For Loops

Use for to repeat code.

When looping over an integer, Nubo iterates from 0 up to that number:

for i in 15 {
    println(i)
}

This prints numbers starting from 0.

Loop Variables

The loop variable is available inside the loop body:

let sum = 0

for i in 10_000 {
    sum = sum + i
}

println("Sum:", sum)

Break

Use break to exit a loop early:

fn x() void {
    for i in 10 {
        if i == 5 {
            break
        }
    }
}

x()

Nil Checks

Use nil to represent a missing value:

let value: string|nil = "Hello"

if isNil(value) {
    println("No value")
}
