No. While jQuery 2 just dropped old-IE hacks jQuery 3 introduced some breaking changes.

You can play a bit with jQuery Migrate plugin to see how much the things are broken and what would it look like to migrate Magento 2 to jQuery 3. What is the value such migration would bring?

Just wondering, why somebody would like to use jQuery for such a complicated project as ecommerce system in 2016 at all? :)

  • i agree that jquery is not the best js lib for ecommerce but i think it will be overkill if i use angularJS framework on magento 2 .

  • Yeah, I've read those blog post before answering but wasn't impressed at all :) As to me, jQuery should be buried in Magento 2 just like PrototypeJS before rather than upgraded. I don't think jQuery+jQueryUI+KnockoutJS+whatever else is bundled too is a bigger overkill than one elegant solution like Angular 2 ;)

  • i agree.. you can use angularJS2+ionic2 to build magento 2 app for your own . For now , M2 support only jQuery and i cant insert angular 2+ionic +knockoutJS or whatever because jQuery is required for M2

  • >>> jQuery+jQueryUI+KnockoutJS+whatever else is bundled too <<< this is what is currently used in Magento 2 already. >>> i cant insert angular 2+ionic +knockoutJS or whatever because jQuery is required for M2 <<< why? to customize core features you'll have to deal with bundled stack but to build your fancy features from scratch you can pick whatever tool better fitting your needs.
