Regex and JavaScript strings

Question

I am working with a set of blood pressure readings, for example

lines[50] = '(523,112)';

and I am using

readings[i] = lines[i].slice(5,8);

to extract the second 3 digit number. How can this be done with a regular expression?

This should give you the desired result. See here for more details

'(523,112)'.match(/,(\d+)/)[1]

Try this:

readings[i] = lines[i].match(/\d+(?=\))/);
