Question

I got problems with this regex. I want to return the first occurrence of this pattern #2344..... But somehow it is returning all occurrences.

var title = '#34 #24 pofejwopwefjopewfjpfeijefow'
pointsRegEx = /(#\d+){1}/;
points = title.match(pointsRegEx);

Your regex is working fine. In your regex, you have (). This creates a group. .match returns an array. The 1st element is the result matched by the entire regex, the other elements are each group from your regex.

.match is returning you ['#34','#34'] because the 1st is the entire regex, and the 2nd is the group in your regex (#\d+).

Note: {1} is not needed, as it will match 1 match by default.

The properties of the array returned from .match is documented here: mozilla docs.
