The method is as follows:
1. Place all <script> tags as close as possible to the bottom of <body> tags.To ensure that the page is parsed before the script is run, minimize the impact on the entire page download
2. Limiting the total number of pages can also improve performance.Whenever a page parsing encounters a <script> tag, it will be used for code execution for a period of time. Minimizing these delays can improve overall performance of the page.
3. Reduce the number of referenced external script files.Each HTTP request creates an additional performance burden, and downloading a 100KB file is faster than downloading four 25KB files. In short, reduce the number of referenced external script files.
4. Download scripts in non-blocking mode.After the page is loaded, then load the JavaScript source code
