You can parse the string to an array using JSON.parse

const loc = '["41.8481","-72.0345"]';
const locArr = JSON.parse(loc);
console.log(locArr);

You can parse to get the desired solution

JSON.parse(location)

first off, i have no idea why you might do this. if you want to edit an array and put it into a string, and then get the array again, just split it with a character. one thing that you could do is this:

let hello = "a|b|c|d|e|f|g";
console.log(hello.split("|")[0]);
//result: "a"

or use JSON.parse. it's easy as 1, 2,

console.log(JSON.parse(location));
