How to Loop Recursively through Hierarchical Objects in JavaScript?

Looping Recursively through Hierarchical Objects

In JavaScript, looping through an object and its descendants can be achieved using a for...in loop. Each iteration accesses the name and properties of the current object.

for (var propertyName in object) {
  // Access the property's name and value
  if (propertyName == "child") {
    // Perform actions on the child property
  }
}

To handle objects with nested properties, you can use a recursive function. This function iterates through the object, recursively calling itself for nested properties:

function loopRecursive(object) {
  for (var propertyName in object) {
    if (typeof object[propertyName] == "object" && object[propertyName] !== null) {
      loopRecursive(object[propertyName]);
    } else {
      // Perform actions on the current property name and value
    }
  }
}

This function will traverse the object, accessing the names and properties of all levels of the hierarchy. By leveraging these techniques, you can effectively loop through complex nested objects.
