JQ Migrate is Installed: How to Remove

2 min

I recently logged into my google search console when I received the message JQ Migrate is installed. It looks something like this.

I searched online and finally came up with a conclusive answer.

JQ Migrate or jQuery Migrate is a drop-in JavaScript library, that allows developers to preserve the backwards compatibility of their jQuery code.

After the update of jQuery 1.9, new lines of code were implemented, but unfortunately, some plugins on WordPress, still depended on these, outdated jQuery 1.9 and earlier version.

So WordPress developers came up with jQuery migrate, to prevent sites from breaking, who were still using outdated plugins, which depended on, jQuery 1.9 or later.
