Description : Using `@return` to output values from SASS functions.
Answer :
`@return` is used inSASS functions to specify the value that the function should output. For example,in a function`@function calculate-rem($px) { @return $px / 16px + rem; }`,`@return` outputs the result of the calculation. This allows the function to be used in other styles or functions, providing dynamic and reusable values.
