Javascript – Capturing all groups in a comma separated list

I am trying to use a regex to match a list of elements separated by a comma in JavaScript.
The regex I use is the following: ([a-z]+)(?:,([a-z]+))*, but I am not able to get all the matched groups, only the first and the last.

I made a regex101 to illustrate my problem: https://regex101.com/r/lIkE8k/5.

Is there something I’m missing?

    Given your sample bold,italic,underlign,blink and what you appear to want, this regex would work

    s*([a-z]+)(?=s*,|s*$)

    This simple regex gives you all capture groups when using matchAll.

    const csv="example,using,several words,and phrases";
const matches = csv.matchAll(/([^,]+)/g);
for (const match of matches) {
    console.log(match[0]);
}
