whenthenReturn

WhenthenReturn is a programming construct that allows for conditional execution of code based on the result of a previous operation. It is commonly used in functional programming languages and some imperative languages that support higher-order functions. The construct typically consists of two main components: a "when" clause and a "then" clause. The "when" clause evaluates a condition, and if the condition is true, the "then" clause executes a specified block of code. If the condition is false, the code within the "then" clause is not executed.

The primary purpose of WhenthenReturn is to streamline conditional logic and improve code readability by combining the evaluation of a condition with the execution of subsequent code in a single, concise statement. This can lead to more expressive and maintainable code, especially in scenarios where multiple conditions need to be checked and corresponding actions taken.

WhenthenReturn is particularly useful in scenarios such as error handling, where a function might return an error value that needs to be checked before proceeding with further operations. By using WhenthenReturn, developers can avoid nested if-else statements and reduce the complexity of their code.

In summary, WhenthenReturn is a versatile programming construct that enhances code readability and maintainability by combining conditional evaluation with subsequent code execution in a single statement. Its use can lead to more expressive and efficient code, particularly in functional programming and scenarios involving conditional logic.
