| 42 * Coment taken from bug 383390: | |
| 43 * | |
| 44 * First, |data| is the final string value produced by the cryptohash. |for (i in | |
| 45 * data)| uses the Mozilla JS extension that iterating over a string iterates over | |
| 46 * its character indexes, so that's 0..length-1 over the hash string. | |
| 47 * | |
| 48 * Returning to the left, the |charCodeAt| gets the value of the character at that | |
| 49 * index in the string. | |
| 50 * | |
| 51 * |slice(-2)| is equivalent to |slice(length of this string - 2)| as a convenient | |
| 52 * way of wrapping around to the other end of a string without doing the actual | |
| 53 * calculation. When provided with only one argument, slice selects to the end of | |
| 54 * the string, so this chomps off the last two characters of the string. | |
| 55 * | |
| 56 * The last-two-characters part clarifies the |"0" +| -- if the Unicode value is | |
| 57 * <10, we have a single-character hex string when we want one that's two | |
| 58 * characters, and unconditionally prepending a "0" solves the problem. | |
| 59 * | |
| 60 * The array comprehension just creates an array whose elements are these | |
| 61 * two-character strings. | |
