        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, N
    Where 0x0030 ≤ N ≤ 0x0039

    Unicode Characters:
    $nn where
    n is one of 0 1 2 3 4 5 6 7 8 9

    Replacement text:
    The nnth element of captures, where nn is a two-digit decimal number in the
    range 01 to 99. If nn≤m and the nnth element of captures is undefined, use
    the empty String instead. If nn is 00 or nn>m, no replacement is done.
