Question

I need to loop through an array using the for clause, but starting at some specific index and just to a maximum of iterations.

The code below does the task, but it looks awful to me: it’s there a better way?

  var offset = 10, max = 5;
  for (var i = 0; (i + offset) < data.length && i < max; i++) {
    doSomething(data[i + offset]);
  }

Answer 1

If I am understanding your question correctly you would just need to initialize i to the offset.

var offset = 10, max = 5 + offset;
for (var i = offset; i < data.length && i < max; i++) {
    doSomething(data[i]);
}

edit: didn’t understand the max at first.
