Why jquery-migrate.min.js Is No Longer Needed

Many developers use the jQuery library for their routine tasks in WordPress. This library has regular updates and new versions. Each version has features with a different implementation. There were times when developers worked in several versions on one website. And the linker was the jquery-migrate.min.js file. But now many users wonder how to disable jquery-migrate.min.js in WordPress.

But why the file that used to be so essential is no longer needed and should be disabled?

It happened because WordPress started using a new jQuery release by default. And jquery-migrate.min.js now is a waste of space that negatively affects the website performance.
