Javascript - Traverse Through The Json Object And Get Each Item Hierarchical Key Including Nested Objects And Arrays

I want to get the values and keys including these as to any JSON objects as a generic method to use even for the complex objects json { 'timezone': 5.5, 'schedule': { 'typ

Solution 1:

const obj = { "timezone": 5.5, "dirs": [ { "watchDir": "Desktop/logs", "compressAfterDays": 50 }, { "watchDir": "Desktop/alerts", "timeMatchRegex": "(.*)(\\d{4})-(\\d{2})-(\\d{2})-(\\d{2})_(\\d{2})(.*)", }] ,"schedule": { "type": "daily", "options": { "hour": 10, "minute": 29 }, 'available': true } };

functioniterate(obj, str) {
  let prev = '';
  for (var property in obj) {
    if (obj.hasOwnProperty(property)) {
      if (typeof obj[property] == "object") {
        const s = isArray(obj) ? prev + str + '[' + property + ']' + '.' : prev + property + (isArray(obj[property]) ? '' : '.');
        iterate(obj[property], s);
      } else {
        prev = (str != undefined ? str : '');
        console.log(prev + property, '- ' + obj[property]);
      }
    }
  }
  return obj;
}

functionisArray(o) {
  return o instanceofArray;
}

iterate(obj);

Solution 2:

Pass on the keys in the recursive call:

 function iterate(obj, path = []) {
   for (let propertyin obj) {
     if (obj.hasOwnProperty(property)) {
       if (typeof obj[property] == "object") {
          iterate(obj[property], [...path, property]);
       } else {
         console.log(path, property , obj[property])
       }
     }
   }  
 }
