How to fix the “$ is not defined” error
If you’re getting the “$ is not defined” error, chances are you’re using jQuery in your code. $ is a shorthand for jQuery, so when you use $, you’re actually using jQuery.
To fix this error, all you need to do is include the jQuery library in your code. You can do this either by downloading the library from the jQuery website or by including it from a CDN (Content Delivery Network).
Once you’ve included the jQuery library, the $ is not defined error should go away and your code should work as expected.
Conclusion

This can be caused by a number of things, but the most common cause is simply forgetting to include the jQuery library in your project. Other causes include using the wrong version of jQuery or using jQuery in a way that is not compatible with your web browser.
