¡list of things to do, and not to do, when developing JavaScript and jQuery!
Just a random JS tips...
1. Optimize selectors for Sizzle’s ‘right to left’ model
$('.class span.class2') - OK
$('#id div.class') - Recommended
2. Don’t load code that isn’t needed or until it is needed
3. Load the framework from CDN or better using Google Code
4. Use lazy loading especially from image/s
5. When emptying nodes: always prefer removeNode() over innerHTML = ''
6. Optimising a selectors
$('div.content') Slower
$('#container div.content') Slow
$('#container').find('div.content') Fast
The best practice is to not use jQuery.
This library is now useless and deprecated with the last framework as React and Angular.
Avoid global namespacing
minification and obfuscation
