It bothered me that so few JavaScript libraries had documentation when I was making jQuery and I made a point to write online docs from the get-go. I’m glad I did! I’m frequently surprised by how few developers will put in the (marginal) extra eﬀort to document their code. So many more people will be able to use and understand if you do!

The great thing about an established library, like jQuery, is it’s hammered on by lots of talented people, transparently improved, and refined by the community. John-David Dalton, Paul Irish https://docs.google.com/document/d/1LPaPA30bLUB_publLIMF0RlhdnPx_ePXm7oW02iiT6o/edit

jQuery is often easier.

Not every website you build will even need JavaScript

Slide 59

Slide 59 text

Some might need a tiny bit, and you’ll decide it’s not worth adding jQuery just for a little piece of code

Slide 60

Slide 60 text

Another website will be much more complex and require something like React / Angular

Slide 61

Slide 61 text

Something else might only need the tip top latest browser support, and you’re happy writing vanilla JS

Slide 62

Slide 62 text

But just sometimes you’ll need a little bit of a hand, or reliable X-Browser support, and jQuery is still a great option.

jQuery is still keeping the barrier low for those new to the web

Slide 68

Slide 68 text

jQuery is still providing a great API and X-Browser solution for those with projects that fit it

Slide 69

jQuery is not a solution for every problem, and nor should it be.

Slide 70

jQuery is still providing a great community that brings people together (like us)
