How to Clone an Object in JavaScript with Object.assign()
In this video, we’ll dive into how to clone an object in JavaScript using the built-in method Object.assign(). The Object.assign() method is a great tool for creating a shallow copy of an object. If you're just starting out with JavaScript, this is one of the most straightforward techniques to duplicate an object while keeping it independent from the original.
What You’ll Learn:
What is a shallow copy?
How to use Object.assign() to clone an object
What happens to nested objects when you use Object.assign()?
Why nested objects are not cloned but referenced
When to use Object.assign() and when to consider deep cloning
This method is perfect for creating a shallow copy of an object, which means copying the top-level properties while maintaining references for any nested objects. Whether you're a beginner or looking to enhance your JavaScript skills, this video will walk you through everything you need to know.
