The Little Book of JavaScript

product_thumbnailI finally bit the bullet, sat down to do some writing again, and had a go at self publishing. The result is The Little Book of JavaScript, a short book containing a few odds and ends which I believe are useful for a novice or intermediate scripter.

It won’t take you through writing a complete application, and I’m assuming that the people who read it are a bit past the “hello world” phase. It’s aimed at people who have dabbled a little, but need a few gaps filled in. The book focuses on raw JavaScript concepts as opposed to their use in any particular framework.

  1. Hi Karl,

    I am a web designer (html, css) and for a long time i have been looking to learn javascript and jquery so that i become a front end dev. I have tried various online resources but can’t manage to stick to the program. Could you suggest some place in Malta that teaches this language please?

    Thanks and regards

  2. Hi Jesper, thank you for your comment. I don’t know any courses in the area, but maybe another commenter might be able to help. I personally believe the best way to learn is to pick a simple project you want to work on, and build it up!
