Bob Stein, the creative mind behind VisiBone, has some up with another great tool for Web developers: JavaScript Cards and Foldouts. The cards and foldouts contain the same information, just presented in different styles. Some find the single-fold card too hard to read because of the small font. The foldouts are easier to read, but come in a set of three.

The purple sheet has the JavaScript language. Though I have an excellent JavaScript book on hand, it helps to have the card because it’s smaller and can be stored nearby plus sometimes I know the syntax, but can’t remember an event’s exact name. Purple covers number, string, boolean, date, function, objects, types, math, array, decisions, and loops.

The orange sheet lists the Document Object Model for windows, documents, forms, layers, events, images, styles, and anchors. In using history, should it be .back() and .forward()? Or should it be .next or .previous? It depends. According to the card, the first set doesn’t work in Internet Explorer 4 and 5. The second set doesn’t work in Netscape 6. Which to alienate? IE 5 users or Netscape 5 users?

The green card provides the literals, classes, repeaters, and submatches of regular expressions. This card helps validate a string’s syntax, search for patterns, or modify strings.

Like the previous VisiBone products, the colors are high quality and the cards are laminated with glare-free material.
