Are you sure this is correct? If so, consider adding `return;` explicitly. This check looks for functions where a `return` statement is found in some execution paths, but not in all. Consider this little piece of code function isBig(a) { if (a > 5000) { return "yes"; } } console.log(isBig(5001)); //returns yes console.log(isBig(42)); //returns undefined The function `isBig` will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return `undefined`. This behaviour may not be what you had intended. In any case, you can add a `return undefined` to the other execution path to make the return value explicit. Loading history...
