One of the most highly request features in the NodeJS runtime environment is being able to use multiple cores — a lot of programmers don't exactly understand the availability of NodeJS packages available to use to help with this issue. The package is worker_threads. This package really does help fix the issue.

With us running the code, it only took approximately 800 milliseconds to run. For such a simple application, that is quite slow. We are able to speed up this application code to just an average of 100 milliseconds. This is a major performance gain with some code refactoring.

Learning how to properly use worker_threads could be an extremely important tool for building anything with NodeJS due to the benefits.

Bringing up the issues we had before with performance we had earlier, the goal is to speed up and make the small application of code above to simply run faster. Since as we all know NodeJS runs everything on a single core – this is by default also, we can change this behavior to use multi-threading.

Bringing our array back without the use of worker_threads to create it will be more clear. Here is a code snippet of how we are going to do this.
