If a RegExp has the
hasIndices), match objects should have an extra property
.indiceswith an array of the character indices that each subgroup matched. The indices array itself has a property
.groupsgiving the matched character indices (or undefined) for each named capturing group.
This doesn't do anything to enable support for the
.hasIndicesproperty, or the returned indices object, if the environment does not support it, but it will populate
.indicesis present, so that the transform-named-capturing-groups-regex and proposal-duplicate-named-capturing-groups-regex plugins can take advantage of that support if it exists.
