Notes
- 1.
Author’s note: Some of my students complain that the alert box looks too much like a “warning,” rather than an information window. For the examples in this chapter, you can use document.write() instead of alert() if that is your preference.
- 2.
In some cases, the parseInt() method, discussed in Chap. 6, might be the preferred choice if the number is to be treated as an integer.
- 3.
Even JavaScript: The Complete Reference, the book referenced in Chap. 1, makes this mistake.
- 4.
Author’s note: I have seen some online references claiming that some implementations of Math.random() might, in fact, occasionally produce a value exactly equal to 1.
