variable-gettersetter.js

/*

//- The Variable the GetterSetter will be operating on
var name = "Ryan Davis";

/**
 * The GetterSetter for [name]
 * ---
 * @param optional new_name - if provided, [name] will be reassigned to this
 * @returns [name]
 */
function nameGetterSetter( new_name ) {
    if (new_name != null) {
        name = new_name;
    }
    
    return name;
}

undefined unless I invoke the function like so nameGetterSetter ("Ryan Davis") then it return's name;

"Ryan Davis"
