JavaScript best practices88
A compilation of best practices and good advice I’ve amassed over the years, much of it learnt the hard way (experimentation and suchlike). Take the advice below to heart and keep it in a part of your brain that has a quick access route so you can apply it without thinking about it. I am sure you will find things to disagree with, and that is a good thing – you should question what you read, and strive to find better solutions. However, I have found that following these principles has made me a more effective developer and allowed other developers to build upon my work more easily.

JavaScript best practices 89

JavaScript is a language we love despite it giving us so much to hate. This is a collection of those very special irregularities, inconstancies and just plain painfully unintuitive moments for the language of the web.
