What are the limitations of destructuring in JavaScript?

What are the limitations of destructuring in JavaScript?

Destructuring in JavaScript is powerful, but it has some limitations. For instance, it can't be used with certain data types like undefined or null, and it may lead to errors if the structure of the object or array doesn't match the destructuring pattern.

Can you give me an example of a limitation?

Sure! If you try to destructure a property that doesn't exist in an object, it will return undefined. For example, if you have const { a } = {} and then try to access a, it will be undefined.

Are there any performance issues with destructuring?

Destructuring itself is generally efficient, but if used excessively in performance-critical code, it can lead to overhead. It's best to use it judiciously.

What about nested destructuring?

Nested destructuring can be tricky. If the nested structure doesn't match, it can lead to errors or unexpected undefined values. Always ensure the structure is correct.
