Nullish Coalescing (??) & Optional Chaining (?.) in JavaScript

1. 1Use the nullish coalescing operator (??) to provide a default value when the left side is null or undefined
2. 2Apply the optional chaining operator (?.) to safely navigate through nested objects and avoid null pointer exceptions
3. 3Test the difference between the nullish coalescing operator and the OR operator (||) in handling null and undefined values
4. 4Configure your code to use the nullish coalescing operator for more precise control over default values
5. 5Run examples to see how the optional chaining operator can simplify your code and reduce errors

Frontend developers and JavaScript engineers can benefit from this knowledge to write more robust and error-free code

💡 The nullish coalescing operator (??) is a more precise alternative to the OR operator (||) for handling null and undefined values
