I opened the developer console and executed jQuery.fn.jquery and I get 1.12.4.
Why does Magento 2 uses the old version even though the latest version is 3.6.0?
I am running a pagespeed report on google page speed insights. It says:
Includes front-end JavaScript libraries with known security vulnerabilities
Can I upgrade jQuery version within Magento 2 to get rid of this?
Also what other packages do I need to upgrade along with jQuery?
What are the pros/cons of upgrading?
