While Loops

A while loop performs a set of statements until a condition equals zero. These kinds of loops are best used when the number of iterations is not known before the first iteration begins.

Examples

// list of numbers from 1 to 10 numbers = 1:10 // variable to sum numbers sum = 0 // loop variable i = 1 // while the variable i is less or equal to the size of numbers while i <= $numbers // add the value of numbers at index i to sum and increment i by 1 sum += numbers(i++) end // output the value of sum sum
