This two codes have the same return

I simplify 

    const getCode = (function () {

        const apiCode = '0]Eal(eh&2'; // A code we do not want outsiders to be able to modify...

            return apiCode;  

    });

    getCode();

    put(getCode());

This one that I got from MDN

    const getCode = (function () {

        const apiCode = '0]Eal(eh&2'; // A code we do not want outsiders to be able to modify...

        return function () {

            return apiCode;

        };

    })();

    getCode();

    put(getCode());
