The main thread
When a browser loads a page, it uses the device’s processing power. This processing is done through the so-called main thread and most major browsers only use a single main thread. The main thread does everything: digests the source code, styling, responds to user events (such as users clicking on links) and ‘paints’ (renders) the page. All of this is done through the main thread – so as you can see, it’s pretty important.
This will become more and more important over time, as websites become more complex and low-end smartphones devices are on the increase.
- What can I move onto a separate thread to free up the main thread?
- How can I provide my users with the smoothest and best possible experience?
