You can see that among other recommendations, GT Metrix to Minify CSS and Minify JS, Merge CSS and Merge JS and minify HTML.

What does minification mean? Code minification is  the process of removing unnecessary characters from the code without changing its functionality. Minifying reduces the amount of code that needs to be transferred = it helps to increase the speed of your side. If you are already working with a development team, please ask them if such measures are necessary. Sometimes, if the JS code is not properly written, minifying can break it.

What is merging? Merging means multiple files with code will be united in one file. And all the requests will be sent to this file only, so merging will reduce the number of requests = speed up your site.
