Should I Pick jQuery?

Just use it. There's no reason not to - it's fairly lightweight, and even if you don't "need" it on this project, you might on the next. Better to stay familiar with it instead of mucking around with bare javascript.

I only use jQuery on Websites, mostly because it comes bundled with Rails. But most of my JavaScript code runs either in specific WebViews, on the server or special OSes like Firefox OS. Especially on mobile I found that jQuery (mobile) slows down everything significantly.

Let's face it, the developer is probably already using jQuery, so why not just depend on it?

Everyone loves a bit of HN-google-twitter juice for publishing some controversial anti-jQuery diatribe.<p><i>yawn</i>

Reasons to use jquery<p>- Other devs in the team are using it<p>- Unless it&#x27;s a small pet project, you will probably need it down the road even if you don&#x27;t need it now<p>- Minified jquery is like 32kb. That means literally nothing in modern web. Unless you are from 1995 using 2G connection, this doesn&#x27;t matter.<p>- Modern browsers are good. It&#x27;s going to handle jquery like a champ. Don&#x27;t worry.<p>- jQuery code is probably better than yours.<p>- Lots of 3rd party libraries have jquery as a dependancy.<p>Reasons not to use jquery and use just javascript<p>- Want to learn javascript<p>- Writing a library or framework and you don&#x27;t want jquery dependancy<p>- Working on a very small website
