Asynchronous Loading: Boosting Page Load Times
By loading non-essential JavaScript and CSS asynchronously, initial page render times can be improved.
1. The Problem with Synchronous Loading
Loading scripts synchronously can block the rendering of a webpage, leading to perceived delays.
2. Async & Defer Attributes
These attributes allow scripts to be downloaded in the background, improving initial page load times.
3. Choosing Between Async & Defer
While both attributes improve performance, their use-cases differ based on script dependencies.
In Conclusion
Asynchronous loading is crucial for improving the time to the first meaningful paint, enhancing the user's perceived performance.
