| 6 <link rel=assert title="For purposes of comparison, all Arrays are greater than
all DOMString, Date and float values; all DOMString values are greater than all
Date and float values; and all Date values are greater than all float values. Va
lues of type float are compared to other float values numerically. Values of typ
e Date are compared to other Date values chronologically. Values of type DOMStri
ng are compared to other values of type DOMString by using the algorithm defined
by step 4 of section 11.8.5, The Abstract Relational Comparison Algorithm, of t
he ECMAScript Language Specification [ECMA-262]. Values of type Array are compar
ed to other values of type Array as follows: |
| 7 |
| 8 1. Let A be the first Array value and B be the second Array value. |
| 9 2. Let length be the lesser of A's length and B's length. |
| 10 3. Let i be 0. |
| 11 4. If the ith value of A is less than the ith value of B, then A is less than B.
Skip the remaining steps. |
| 12 5. If the ith value of A is greater than the ith value of B, then A is greater t
han B. Skip the remaining steps. |
| 13 6. Increase i by 1. |
| 14 7. If i is not equal to length, go back to step 4. Otherwise continue to next st
ep. |
| 15 8. If A's length is less than B's length, then A is less than B. If A's length i
s greater than B's length, then A is greater than B. Otherwise A and B are equal
