RegExp.prototype[Symbol.replace] works with named capture references as expected.

(string replacement)

Table: Replacement Text Symbol Substitutions
|
||||||
|
|
||||||
|
Unicode Characters: $<
|
||||||
|
Replacement text:
|
||||||
|
1. If namedCaptures is undefined, the replacement text is the literal string $<.
|
||||||
|
2. Else,
|
||||||
|
a. Assert: Type(namedCaptures) is Object.
|
||||||
|
b. Scan until the next > U+003E (GREATER-THAN SIGN).
|
||||||
|
c. If none is found, the replacement text is the String "$<".
|
||||||
|
d. Else,
|
||||||
|
i. Let groupName be the enclosed substring.
|
||||||
|
ii. Let capture be ? Get(namedCaptures, groupName).
|
||||||
|
iii. If capture is undefined, replace the text through > with the empty String.
|
||||||
|
iv. Otherwise, replace the text through > with ? ToString(capture).
