Changing Values of a Deeply Nested JavaScript Object

JavaScript provides us with powerful ways to manipulate objects, but working with deeply nested structures can be tricky. If you have a complex object and need to change all values of a specific nested level, you may find yourself in a bit of a dilemma. Today, we'll tackle the problem of altering values within a deeply nested object using a defined path.

The Challenge

Imagine you have the following JavaScript object structure:

Solution 1: Recursion

One effective method is to create a recursive function that navigates through the object based on the specified path. Here is how you can implement that:

Step-by-Step Function Explanation

Define the Function: We create a function named getUpdatedObject that accepts the original object, the path to the target object, and the new value.

Calculate Target Level: The function computes the target level based on the length of the path array.

Recursive Helper Function: A nested helper function, setValuesOfPath, is used to traverse the object and update the values.

Update the Values: When the correct level is reached, all the values in the specified object are updated to the new value.

Implementation

Here’s the complete code using recursion:

Solution 2: Utilizing Lodash

For those who prefer using libraries, the popular utility library Lodash provides an elegant solution to the same problem. Here’s how you can use Lodash to change nested values:

Step-by-Step Function Explanation

Install Lodash: Ensure that Lodash is included in your project. You can use it via CDN or npm.

Get and Update Values: Use the _.get method to retrieve the target object dynamically and then update its values.

Implementation

Here’s how you can do it with Lodash:

Conclusion

Changing values in deeply nested JavaScript objects can be streamlined by employing recursive functions or utilizing powerful utility libraries like Lodash. By understanding these methods, you can efficiently manage complex data structures in your JavaScript applications. Embrace the power of recursion or leverage libraries to enhance your code and solve challenges effectively.

Now, feel free to try these solutions in your own projects and see how they can simplify your coding tasks!
