Question

I am fetching some values in a forEach clause

 data.forEach(function(content){
  ...
  controller.setAttribute(value from data);
  ...}

This works for me. But data loop iterates for close to 20 times. And my controller can take only 5 values. Hence my controller in above example is taking last five values.

How can I limit my data to exit after reading first five values. I need to be having some counter there right?

Or is there any other way for controller to read only first five?

Answer 1

You can pass an index argument after the value argument and use that:

data.forEach(function(content, index){
   if (index < 5) {
       controller.setAttribute(value from data);
   }
});
