Zepto.Js

What do you like best?

I have used Zepto in a project where I needed jQuery-like syntax but way less clutter and a minimal footprint. jQuery has become quite the behemot in recent versions, and sometime I feel it is a bit overblown for most of the normal use cases (at least for me). Zepto allowed me to change JS framework and save 100 Kbytes without leaving my comfort zone as a jQuery user, as the syntax is almost 1:1.

What do you dislike?

It has a few limitations compared to jQuery, and real world tests have proved it is actually a little bit slower, despite being so much smaller (and thus loading faster). Also, don't expect to seamlessly be able to switch frameworks when using third party plugins requiring jQuery, chances are they won't work.

Recommendations to others considering the product:

When using Webkit browsers or web views, Zepto can help achieving the desired functionality using the same skill set in a fraction of the space taken by jQuery as it is leaner, but a web developer needs to be aware of some limitations.

What problems are you solving with the product? What benefits have you realized?

Zepto helped me tackle a particular digital signage project where jQuery was out of scope. It turned out pretty well, and it's till in use on more than 150 clients in a primary italian airport.
