This is one of the key reasons

Another important parameter is the execution order. Internet surfing software displays a page to the user from top to bottom, creating DOM components as it moves through the HTML file. If the developer places the tags at the end of the document, the JS will be opened at the very last moment. As a result, it will not have much impact on the critical rendering path.
And, accordingly, vice versa, when placing a tag at the very beginning of the page, the browser will execute this script first, and then display the rest of the information. why loading is performed extremely slowly and with some problems. For this reason, it is recommended to move the location of non-critical scripts to the very end of the page (advertisements, analytical tools, counters, and other similar ones).
Another option for optimizing the process is asynchronous loading. This is a more correct method for solving problems with displaying "slow" third-party scripts. Using the async attribute oman consumer email list allows the browser to not wait for loading, executing the specified scripts to display the rest of the page components.
If the scripts written depend on each other, it is recommended to use the defer tag. With its help, it is possible to perform asynchronous loading of the page, but taking into account a certain sequence of script execution.
Summing up
This article covered all the main ways to connect JS files to html documents. Using these methods allows you to integrate various scenarios into web pages, which allows owners to conduct analytics, control the number of user clicks on the site, and perform other tasks.
JavaScript optimization is an important tool that provides the opportunity to implement the necessary ideas without making the site heavier and without making users wait a long time for it to load. A comprehensive approach will help develop web resources, integrating JS into them without negative consequences for the target audience, its stay on the site.
