of the most recent match.index Holds the string index value of the first character in the most recent
pattern match. This property is not part of the ECMA standard, though
it is supported widely. Therefore it may be better to use the length
of the regexp pattern and the lastIndex property to calculate this
value.

lastIndex Integer specifying the position in the string at which to start the next
match. Same as the instance property, which should be used instead.

the most recent match.leftContext String containing the text to the left of the most recent match.
