What does it mean $1Z in regular expression

Question

I'm not familiar with regex, but I have the following string

d.$filter = d.$filter.replace(/TutoringSince le '(.+?)'/g, "TutoringSince ge $1Z");

Is anybody know what does it mean this Z char after $1 ?

$1 is a reference to the first group - in this case: (.+?)

Z is just a Z letter.

Literal, capital letter Z. i.e. it will add Z at the end of the first captured group. – Maria Ivanova Jul 01 '16 at 08:09
@BorHunter It is a regular text like `TutoringSince...` – hsz Jul 01 '16 at 08:09
@MariaDeleva thank you – BorHunter Jul 01 '16 at 08:10

It replaces the captured text in the d.$filter, with TutoringSince ge, plus itself then adds a Z. I.e. the text

TutoringSince le 'whatever'

would turn into

TutoringSince ge whateverZ

"The captured text" would be anything inside the single quotes.
