It gives advice to avoid common mistakes and subtle bugs, as well as performance issues and bad practices, that non-expert JavaScript programmers may encounter on their endeavours into the depths of the language.JavaScript Garden does not aim to teach you JavaScript.
Former knowledge of the language is strongly recommended in order to understand the topics covered in this guide.
