Function Example

// Example on how to define custom functions

// sum() function
sum = function(list_of_numbers) {
    total = 0;
    foreach (list_of_numbers as number) {
        total = total + number;
    }
};

// range() function
range = function(start_number, end_number, step = 1) {
    result = [];
    number = start_number;
    while (number <= end_number) {
        arrayPush(result, number);
        number = number + step;
    }
    return result;
};

// Calling functions
log(sum(range(1, 9)));
