A lot of people have been asking how to defer render blocking javascript in order to speed up their site. So I was curious about just how much javascript people use on their sites.

Since this is really something that's done by your plugins and themes as opposed to something you do yourself, you probably have no idea what the answer to this is. The tools I use to find out is https://gtmetrix.com/ and https://www.webpagetest.org/ although for this purpose GTMetrix is probably the easier of the two.

Once you run a scan of your site it will give you a list of problems to fix. If you click on “Defer parsing of Javascript” it will give you a list of the files and the total size of these files. If you're willing to share and compare with other members, add a comment with the total number of files and the total size of these files, and maybe even your pagespeed scores. Thanks.

Every time I look at these codes I get completely lost because I have no idea how to fix it all up.
Regardless, my loading time is usually under a second so I don't stress too much.

Yeah. That's a pretty good benchmark. If you can keep your site under a second, you're doing pretty awesome.

Be careful with JavaScript. Along with Visual Basic Script it is subject to infection!

Well you have to be careful with all your efforts online not to make sure that you use proper security protocols.

Now this is the way to do this - first you have to add a plugin by WP and then you have to paste a certain code into the plugin and then it will work but as of yet i have no guts to try it!!!

Don't worry. I spent years railing against the use of Javascript. The web has decided to disagree with me unfortunately. However, if you get the results you want without that's probably the way to go. :)

Just a heads up this can get a little messy, so be careful. I'll put some training up when I can that will help walk you through things, but I won't get access to putting up training for another couple months yet.

My experience with these javascript errors is that it is impossible to fix them. So many texts exist, and after trying many I just gave up. This is for people who really understand the thing.

You do not need the tools you mentioned. Google Speed Insight tool will give you the same, together with instructions how to proceed. Problem is to understand them.

Yeah. This is actually the biggest problem I have with Javascript. It's up to the browsers to run it and so you never know if its going to work properly. A lot of the web is heading in this direction unfortunately.

The GTMetrix tool actually includes the information from Google PageSpeed and WebPageTest.org is a project that partners with Google. The reason I recommended them is because they give much more detailed information about your site. But you're right the PageSpeed tool works well too
