Today’s consumers won’t wait more than 5 seconds for a webpage to load before bouncing to another site. The digital landscape is increasingly competitive, and a fast, steady online experience is the expected standard.
Anything less puts your business at a serious disadvantage, because no matter how engaging the content, features, or functionality, if your site is slow, many people aren’t likely to ever see them.
Several factors can affect your website’s performance, including large file sizes, hosting issues, widgets, and plug-ins, among others. Another common culprit is heavy functionality.
When time-consuming tasks like complex renderings, advanced filtering, or manipulation of a large amount of data are involved, this type of structure can block the main thread and cause performance issues. That’s where “web workers” come in.

What Is a Web Worker?
Here’s a real-world metaphor: You have a big presentation coming up in two days, and you haven’t started the PowerPoint deck. You know you can get the information together, but making the slides look good will take more time than you have.
You ask a graphic designer on your team to help with that aspect of the deck, freeing you up to focus on the content and helping you create a high-quality finished product on time.
In this scenario, you’re the main thread and the designer is a web worker. In technical terms, a web worker allows JS to be multi-threaded. It’s a script that runs in the background, in parallel with the main thread, and performs lengthy, intensive tasks. It’s a built-in, ready-to-use feature in HTML5.
Here’s how it works: When a user taps or clicks, that triggers an action, or an “event.” In response to that event, JS executes certain code, called an “event handler,” to present the user with the desired result.
If the main thread can’t produce that result quickly, it creates a web worker to take it on. If the main thread needs to pass values to the web worker, or vice versa, they interact through “message events.” This allows the web worker to stay in sync with the main thread and share information to complete the task.
Web workers are a boon to the JS technology. They significantly reduce the load and burden on the main thread, increasing the performance of the page and improving the user’s experience.
