Please show an input example and expected output. You may want to look at destructuringmplungjan– mplungjan2017-11-16 09:26:48 +00:00Commented Nov 16, 2017 at 9:26

@mplungjan I agree. It is not clear what we are trying. I want to see the desired i/o.Niklas Rosencrantz– Niklas Rosencrantz2017-11-16 09:30:59 +00:00Commented Nov 16, 2017 at 9:30

Simply split by /\[|\]/ and the remove the empty strings.
var output = "post_address[location][area]".split(/\[|\]/).filter((s)=>s.length > 0);
console.log(output);

You can use regexp like this :
var re = /^(\w*)\[(\w*)\]\[(\w*)\]$/gi;

Use Lodash:
const str = "post_address[location][area]";
const output = _.compact(_.split(str, /\[|\]/));
console.log(output);<script src="https://cdn.jsdelivr.net/npm/[email protected]/lodash.min.js"></script>

There is the shorter way
It is actually the same as
'post_address[location][area]'.split(/[^\w]+/).filter(i => i)
console.log(
'post_address[location][area]'.match(/(\w+)/g)
);
console.log(
'post_address[location][area]'.split(/[^\w]+/).filter(i => i)
);
