What are some common mistakes when using wrappers in JavaScript?

Some common mistakes include not understanding the difference between primitive values and wrapper objects, using wrappers unnecessarily, and failing to handle type coercion properly.

Can you explain the difference between primitive values and wrapper objects?

Sure! Primitive values are the basic data types like strings, numbers, and booleans. Wrapper objects, like String, Number, and Boolean, are objects that wrap these primitive values to provide additional methods and properties.

Why should I avoid using wrappers unnecessarily?

Using wrappers unnecessarily can lead to performance issues and unexpected behavior, especially when comparing values or performing operations that expect primitive types.

What is type coercion and how does it relate to wrappers?

Type coercion is the automatic conversion of values from one type to another. Wrappers can complicate this process, as they may lead to unexpected results when JavaScript tries to convert between types.
