Review Summary

Hey there! 👋 Thanks for your submission. The code looks good overall, but there's a small hiccup: the if (this[i] !== null && this[i] !== undefined) condition inside your loop might cause your custom join method to behave differently than the standard Array.prototype.join() method when it encounters null or undefined elements. According to MDN (Array.prototype.join()), null and undefined elements should be treated as empty strings. Could you adjust your code to align with this expected behavior? Also, remember to use the += operator for string concatenation as per the code style guidelines. 😉

Consider how null or undefined elements should be handled according to the standard join method. The current implementation might not align with the expected behavior. Check Array.prototype.join() for the expected behavior.

Consider using plus operator with assignment operator = if you want to add something to existing value.
