As lots of developer, I use jQuery nearly all the time. It makes development quick and easy. However, sometimes I work on very simple build where it will be possible to avoid loading jQuery.
There are lots of article on the web “anti-jQuery” showing other javascript library with better performance, shorter load time, or vanilla script which does the same job as jQuery plugins.
I will share here useful links to avoid using jQuery all the time when you don’t really need it.
No dependencies plugins
I love this website youmightnotneedjqueryplugins.com with some really good plugins (calendar, scrollbar, etc.)
By the same people youmightnotneedjquery.com tells you how to do it in pure javascript
Light alternative to jQuery
Just a start… I will add more in the future.
