Loops/For with a specified step: Difference between revisions

=={{header|Wren}}==

There is currently no direct way to incorporate a step into a ''for'' loop but we can simulate it by declaring a second variable at the start of the loop which maps the loop variable to the value we want or we can simply use a ''while'' loop instead.

for (i in 1..10) {

var j = 2*i - 1

A further and more general approach is to use a wrapper class (such as the one in the above module) which can iterate over any sequence in a stepped fashion using Wren's ''iterator protocol''.
