We can’t go on like this. Using prompt() and alert() for all input and output (as we did in the previous articles is unwieldy and just plain dumb when there are many ways of skinning this particular cat.

But in JavaScript, the index of an array need not be a number, it can also be a word (more…)
In the previous article I sang the praises of JavaScript as an advanced programming language, then proceeded to demonstrate some rather unsophisticated methods of input/output. In hindsight my examples didn’t support my argument too well. In this article I will rectify things by having a good hard look at JavaScript arrays. (more…)
For quite some time I have not had a high opinion of JavaScript. This is probably because in the late 90s I spent far too much time trying to get so-called Dynamic HTML to work reliably on the version 4 flavours of Netscape and Internet Explorer. And also because JavaScript is far too often used in stupid and annoying ways on the Web, to name a few: pop-up windows, window resizing, dialog boxes, cursor trails, and JavaScript-only links and forms.
