I don't hate JQuery
Should I hate a library or framework ? My answer is “No”. Every library or framework is created for a reason. If that matches your needs you can use it in your projects otherwise do it on your own. Nothing to be hated here.
fetch API. That made handling HTTP request easier, That API came after JQuery
ajax introduced. If you need old browser support you can use JQuery.
If you need to scale your application for millions of users, you don’t want to add extra JS file to the web page, that’s fine. But if you have a small number of user for your application and you don’t need optimization for million users why don’t use JQuery ?
Use framework or libraries according to your need or project requirements. No hate please, Spread love.
