javascript: regex for get string in array of quoted string with separator

Question

I have a string like this:

"foo", "bar", "baz"

I want, with a regex, get the single string;

["foo", "bar", "baz"]

This is my code:

var re = new RegExp('"(?:[^"])*"', 'g');
var match = re.exec('"foo", "bar", "baz"');
console.log(match);

but doesn't check for the separator , and return only foo...

Your string looks a lot like an array. Is it really `'"foo", "bar", "baz"'`? — ggorlen, Sep 10 '18 at 17:05
`re.exec` only returns one match, you need to run it in a loop. Also, `(?:[^"])` = `[^"]`. — Wiktor Stribiżew, Sep 10 '18 at 17:06
Here's an idea. The only caveat is that it allows a trailing comma too. var re = new RegExp('"([^"]*)",?', 'g'); var match = re.exec('"foo", "bar", "baz"'); while (match) { console.log(match[1]); match = re.exec('"foo", "bar", "baz"'); } — Steven Spungin, Sep 10 '18 at 17:11
Why marked as duplicate? That does not solve OP question. Annoying that I spent time on this and then can't answer! — Steven Spungin, Sep 10 '18 at 17:12

You can choose to use split(/,\s+/) and replace() for that output:

var str = '"foo", "bar", "baz"';
var res = str.split(/,\s+/).map(item=>item.replace(/"/g, ''));
console.log(res);

_"and `trim()` ..."_ - or a different separator for `.split()` – Andreas Sep 10 '18 at 17:07
@Andreas yeah correct. You are right. – Ankit Agarwal Sep 10 '18 at 17:11

You could add brackets and parse the JSON.

var string = '"foo", "bar", "baz"',
    array = JSON.parse('[' + string + ']');
    
console.log(array);

Here's a solution that chops off the leading/trailing quotes and splits on the delimiter:

const s = '"foo", "bar", "baz"';
console.log(s.slice(1, s.length-1).split('", "'));
