Benchmark: JSON.parse vs String.substring vs String.match for fetching one value

Script Preparation code:

var ob = `{"aenderungen":[],"_id":"64c0fc4abd2c8bd76c9553f2","name":"Maxis","geburtsdatum":"2023-08-02T00:00:00.000Z","ICD10Code":"k k k k k ","position":0,"empfangsdatum":"2023-07-26T10:58:18.716Z","hinzugefügtVon":"6498bf3b2afb897aa26d18e6","infos":{"berichte":"ggg","puls":"hallo yazn "},"positionarr":[0,0],"stationen":[],"__v":0}`

Tests:

JSON.parse()
var value = JSON.parse(ob)._id;
String.substring
const value = ob.substring(25,49);
String.match
const value = ob.match(/"_id":"(\w+)"/)[1]
