16. Repeat, for each result in results,
[...]
m. If functionalReplace is true, then
[...]
n. Else,
i. Let replacement be GetSubstitution(matched, S, position,
captures, replaceValue).
[...]
21.1.3.14.1 Runtime Semantics: GetSubstitution
Code units:
0x0024, N
Where 0x0031 ≤ N ≤ 0x0039
Unicode Characters:
$n where
n is one of 1 2 3 4 5 6 7 8 9 and $n is not followed by a decimal digit
Replacement text:
The nth element of captures, where n is a single digit in the range 1 to 9.
If n≤m and the nth element of captures is undefined, use the empty String
instead. If n>m, no replacement is done.
