Convert string to object - Javascript

Question

I have a string and would like to convert it to an object based upon certain conditions.

My string here is '?client=66&instance=367&model=125'. I would like to convert it to an object like

{
 "client": 66,
 "instance": 367,
 "model": 125
}

I have managed to achieve it but wanting to find a better solution. Below is my implementation:

const path = '?client=66&instance=367&model=125';
const replacedPath = path.replace(/\?|&/g, '');
const clearedPath = replacedPath.match(/[a-z]+|[^a-z]+/gi).map(str => str.replace(/=/g, ''))
var output = {}
clearedPath.forEach((x, i, arr) => {
 if (i % 2 === 0) output[x] = Number(arr[i + 1]);
});
console.log(output)

Please advice. Any help is highly appreciated.

Answer 1

Object.fromEntries(
 'client=66&instance=367&model=125'.split('&').map(it => it.split('='))
)

just delete the first '?':

let src = '?client=66&instance=367&model=125';
if (src[0] === '?') src = src.substring(1);
const obj = Object.fromEntries(
 'client=66&instance=367&model=125'.split('&').map(it => it.split('='))
);
console.log(obj);

prints {client: "66", instance: "367", model: "125"}
