Javascript – Trying to use regex after already using regex once

I have the following code and I’ve got the id and name value in its own square bracket as shown below. How can I access the value of id and name?

let data = "[[id=3, name=BOX-3, description=test, comment=test, locationId=5, capacity=null]];"

        let id = data.match(/(?<=id=)d+(?=,)/g);
        let name = data.match(/(?<=name=)[w|-]*/g);

console.log(data);
console.log(id);
console.log(name);


console.log(id.match(/(?<=[)[^][]*(?=])/g) );

//console.log(idVal);

    You can destructure the result to get the match.

    let data = "[[id=3, name=BOX-3, description=test, comment=test, locationId=5, capacity=null]];"
let [id] = data.match(/(?<=id=)d+(?=,)/g);
let [name] = data.match(/(?<=name=)[w|-]*/g);

console.log(id);
console.log(name);

    let data = "[[id=3, name=BOX-3, description=test, comment=test, locationId=5, capacity=null]];"

let id = data.match(/id=(d+)/);
let name = data.match(/name=([w|-]+)/);

if (id) {
  id = id[1]; // Extract the captured group value
}

if (name) {
  name = name[1]; // Extract the captured group value
}

console.log(data);
console.log(id);
console.log(name);
