Load and run of high-performance JavaScript

JavaScript's performance in the browser can be considered the most important usability issue that developers have to face. This problem is complicated by the blocking features of JavaScript, that is, when JavaScript is running, other things cannot be handled by the browser. In fact, most browsers use a single process to handle multiple tasks, such as UI updates and JavaScript runs, while only one task can be executed at a time. How long JavaScript has been running, and how long it will wait befo
