Using Javascript node.js how do I parallel process For loops?

Question

I only started to learn javascript 2 days ago so I'm pretty new. I've written code which is optimal but takes 20 minutes to run. I was wondering if there's a simple way to parallel process with for loops e.g.

for (x=0; x<5; x++){ processor 1 do ...

for (x=5; x<10; x++){ processor 2 do ...

Answer 1

Since the OP wants to process the loop in parallel, the async.each() function from the async library is the ideal way to go.

I've had faster execution times using async.each compared to forEach in nodejs.
