Sometimes you use a pattern so frequently that you don’t realize that other people might not know about it. Here’s the most recent one for me — I was surprised that this wasn’t being used in the last few codebases I’ve seen:
If you’re using Backbone.js, instead of writing
view.$el.find('span.timestamp')
or worse
$(view.el).find('span.timestamp')
or
$('span.timestamp', view.$el)
Backbone provides a $ method such that you can simply write
view.$('span.timestamp')
It’s less to type and it doesn’t hurt readability.
