Return statements in JavaScript allow functions to send values back to the calling code, enabling modular and reusable logic, making code more efficient and maintainable. By using return statements effectively, developers can write robust and scalable applications, creating functions that perform complex calculations or operations and returning results for further processing.
Return statements in JavaScript enable functions to send values back to the caller, allowing for reusable and modular code. They can return any data type and are essential for efficiency and performance. There are two types of returns: implicit (returns undefined) and explicit (specifies a value). Best practices include using explicit returns, returning consistent data types, and avoiding complexity.
