        More Info

        Declaring a variable only to immediately return it is considered a bad practice because it adds unnecessary complexity to the code. This practice can make the code harder to read and understand, as it introduces an extra step that doesn’t add any value. Instead of declaring a variable and then immediately returning, it is generally better to return or throw the value directly. This makes the code cleaner, simpler, and easier to understand.
