Searching for all instances of "key" in an object with TypeScript.

obj-search.ts

class Utils {
  static search(name: String, obj: any, results: Array<any>) {
    for (var key in obj) {
      if (obj.hasOwnProperty(key)) {
        const value = obj[key];

        if (key == name) {
          results.push(value);
        }
        else if (typeof value === 'object') {
          Utils.search(name, value, results);
        }
      }
    }
  }

  static searchByNodeType(type: String, obj: any, results: Array<any>) {
    for (var key in obj) {
      if (obj.hasOwnProperty(key)) {
        const value = obj[key];

        if (typeof value === 'object') {
          if (value['_type'] == type) {
            results.push({ "name": key, "value": value });
          }
          else {
            Utils.searchByNodeType(type, value, results);
          }
        }
      }
    }
  }
}
      
// EXAMPLE USAGE (Create a results array to store output.)
let results: Array<any> = [];

Utils.search("_power", org, results);
console.log(results);

results = [];
Utils.searchByNodeType("hotdrop", org, results);
console.log(results);
