Question

How do I use JavaScript regular expression to match the value of a string after an underscore, but ignoring an s at the end if there is one.

For example: abcdefg_hijk and abcdefg_hijks should both return hijk.

Answer 1

Something like the following should give you what you’re after:

var str = 'abcdefg_hijk';
var regex = /_(\w*)/;

str.match(regex)[1];  //returns hijk
