The jQuery library is one of the most popular on the web. About 70 million active websites use it. In the past, jQuery was used to facilitate cross-browser code writing.
Websites that previously used jQuery code and modifications will continue to operate but the library will not be connected to new projects.
If you are using third-party code on your Tilda website, please take these changes into account. Chances are you may want to update the code and remove dependence on the jQuery library.
