Why are wix websites have many warnings and errors? On a regular website there's more than 70 warning, and if you're using the developer tools on your website you probably saw many errors as well.
These warnings and errors are causing the performance to fall dramatically, and makes the loading time longer, what if you wanted to use a custom page with a lot of functions and conditional statements? Do you know how much slower the website will get?
Check out this page, it has an average loading time of 7.8 seconds and can reach up to 9.4 seconds when the user is logged in.
Using functions and conditional statements is normal, so it can't be an excuse for slowing down the website and downgrade its performance, I don't notice any slow downs on performance when visiting Amazon or really any big websites, and if that's my website performance without any traffic, how horrible the performance will be when the website is being hit with many visits at once?
Visit the above page and check the loading time from the developers' tools.
