Control Flow

Conditional branching statements.

let age = 18;

# Simple if
if (age >= 18)
    print("Adult");
end

# If-else
let score = 75;
if (score >= 60)
    print("Pass");
else
    print("Fail");
end

# Else-if chain
let grade = 85;
let letter;
if (grade >= 90)
    letter = "A";
elsif (grade >= 80)
    letter = "B";
elsif (grade >= 70)
    letter = "C";
elsif (grade >= 60)
    letter = "D";
else
    letter = "F";
end
print(letter);  # "B"

Repeats while a condition is true.

let i = 0;
while (i < 5)
    print("Count: " + str(i));
    i = i + 1;
end
# Output: Count: 0, 1, 2, 3, 4

Iterates over collections or ranges.

# Iterate over array
let fruits = ["apple", "banana", "cherry"];
for (fruit in fruits)
    print(fruit);
end

# Iterate with range
for (i in range(0, 5))
    print(i);  # 0, 1, 2, 3, 4
end

# Range with step
for (i in range(0, 10, 2))
    print(i);  # 0, 2, 4, 6, 8
end

# Nested loops
for (i in range(1, 4))
    for (j in range(1, 4))
        print(str(i) + " x " + str(j) + " = " + str(i * j));
    end
end

Ruby-style postfix conditionals for concise one-liners.

let x = 10;
print("big") if (x > 5);

let y = 3;
print("small") unless (y > 5);

let status = "active";
print("Welcome!") if (status == "active");
print("Account locked") unless (status != "banned");

Inline conditional expression.

let x = 10;
let size = x > 5 ? "large" : "small";
print(size);  # "large"

# Nested ternary
let grade = 85;
let letter = grade >= 90 ? "A"
             : grade >= 80 ? "B"
             : grade >= 70 ? "C"
             : grade >= 60 ? "D"
             : "F";
print(letter);  # "B"

Exits the current loop immediately.

Skips to the next iteration of the loop.
