Regex produces odd results in string processing

This particular JavaScript regular expression:

homework.description = (homework.input.match(/((\(((\S\s?)\)?)*)|(about( \w*)*))/i));

When applied to the text:

potato (potato)

Produces this unexpected output:

(potato),(potato),(potato),o),o,

This result is quite strange. The expected outcome should be:

(potato)

Answer №1

I have discovered a solution that works for me. Thanks to @EthanBrown for providing a more simplified regex!

homework.description = String(homework.input.match(/\((.*)\)$|about\b(.*)$/i)).split(',')[1]
if(homework.description === null || homework.description === ""){
        homework.description = String(homework.input.match(/\((.*)\)$|about\b(.*)$/i)).split(',')[0]
}
