Why Should You Optimize JavaScript?
One of the most important steps for fast websites is reducing the number of HTTP requests. You can do so by combining several scripts in one. This is super useful if you have many plugins on a website. After you install any plugin, JS scripts are flooding your website pages, even where they are not needed. Thus, extra requests are sent to the server, and the website lags. If PageSpeed Insights shows the problem with low page speed, then you definitely need to optimize JavaScript in WordPress.
