JavaScript files become lighter by deleting and compressing line breaks and comments that are unnecessary when a computer loads the JavaScript file. Additionally, tasks that cause delays of 50 milliseconds or more while the browser loads and renders JavaScript are considered "long-code tasks" and can lead to a lower FID. However, tasks that are long in code can be split up, which can reduce the time it takes to process JavaScript.


Using a Web Worker script JavaScript is usually processed spain telegram phone number list in an area called the main thread in the browser, where user actions and content rendering are handled. Therefore, when a large amount of JavaScript is concentrated on the main thread, the load on the browser increases and it is unable to respond to user input, which causes FID. However, by using a script called a Web Worker, JavaScript can be executed on a background thread instead of the main thread.


By processing JavaScript on a background thread, the load on the main thread is reduced, leading to improved FID.
