Control Flow — Kria Documentation

Conditional Statements

Control program execution based on conditions using if, elseif, and else.

set age = 25
if (age >= 18) {
    print("Adult")
}

set score = 75
if (score >= 90) {
    print("A")
} else {
    if (score >= 80) {
        print("B")
    } else {
        print("C")
    }
}

Each branch is evaluated only if the previous condition is false. All branches are optional.

Execute a block repeatedly while a condition is true:

set counter = 0
while (counter < 5) {
    print(counter)
    set counter = counter + 1
}

set sum = 0
set i = 1
while (i <= 10) {
    set sum = sum + i
    set i = i + 1
}
print(sum)

The loop repeats until the condition becomes false. Ensure your condition will eventually be false to avoid infinite loops.

Iterate over arrays with for item in array, or over object keys with for key, value in object.

set items = [10, 20, 30]
for item in items {
    print(item)
}

set user = { name: "Kria", age: 5 }
for key, value in user {
    print(key)
    print(value)
}

Arrays use single iteration variable; objects use two (key and value). The loop processes each element in order.

Control loop execution with break (exit immediately) and continue (skip to next iteration).

set i = 0
while (i <= 100) {
    if (i >= 50) {
        print(i)
        break
    }
    set i = i + 1
}

set nums = [1, 2, 3, 4, 5, 6]
for n in nums {
    set remainder = n - ((n / 2) * 2)
    if (remainder == 0) {
        continue
    }
    print(n)
}

break exits the innermost loop. continue jumps to the next iteration.
