Javascript Replace Regex - String with random number

Question

I need to replace a string that has a random number in it.

This is the string

[Async Chat Thread - #<randomNumber>/INFO]:

Here is what i have tried. the \d was one of my many attempts.

str.replace(/\[Async Chat Thread - #\d\/INFO\]:/gi, "");

I am very new to regex so if someone could please explain how i go about this or what i may be doing wrong.

\d matches a single digit. Do you want to match more than one digit? — Felix Kling

Then you need to specify repetition: regular-expressions.info/repeat.html . — Felix Kling

\d only matches a single digit. If you want to match one or more digits, you need to specify repetition. For example + denotes the occurrence of the previous group one ore more times:

\d+

OTOH, {x, y} specifies that the previous group has to occur at least x and at most y times:

\d{1,3}
