javascript - What's the meaning of /gi in a regex?

I see an line in my JavaScript code like this:

var regex = /[^\w\s]/gi;

What's the meaning of this /gi in the regex?

Other part I can understand as it accepts a group of word and spaces, but not /gi.

Answer

g modifier: global. All matches (don't return on first match)

i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])

In your case though i is immaterial as you dont capture [a-zA-Z].

For input like !@#$ if g modifier is not there regex will return first match !See here.

If g is there it will return the whole or whatever it can match.See here
