JAVASCRIPT GUIDE
|
At the moment this guide is still in the process of being written.
Pages will be added as soon as they are completed.
This JavaScript guide contains introductory information about the language. Using simple examples, and larger 'end of topic' programs, this guide takes you step-by-step through most of the JavaScript code you will need to know (all of the code used in my scripts is covered here).
Like the HTML guide, this guide is an introduction. No previous knowledge of programming is necessary.
This course should put you in a position to have confidence in writing and implementing additional functions into the scripts you create.
Further references can be obtained from my resources links page.
