Kudos to Treasure Porth for the fantastic content—her detailed explanations of each Javascript method in every challenge were top-notch 💯. I highly recommend this course to anyone who's simply looking to level up their Javascript game.

Excellent format of the course! Using several projects to build on one another is a great way to reinforce skills and the topics were engaging. Also great end point video to build upon what was taught and wrap up the course.

The toString() method returns a string as a string.

Sorry but going over JS methods such as toString, join, split, sort etc is not an interview prep. Noone asks me in the interview these silly questions. Interview questions include building out a dropdown, or a modal window, or a writing a dynamic programming algorithm. This is very beginner JS course pretty much. Described anagram algorithm is also not the best, because when you need to sort your split array and then join it back, you run into time complexity of O(n log n). There are better ways to do it. If you write a solution in the interview using built-in methodsL split, sort, and join, you will simply be likely asked to think if there is a better way. Saying that, it is always good to mention that this is one way of doing it, so interviewer sees you know your methods, but this is absolutely not the best solution to anagram problem. It is not a bad course. But the title is very wrong. It should be called "Beginner JS Course" or "Master your javascript methods" course may be, but definitely not "JavaScript Interview Challenges". 2 start due to this. But it still would be really useful course for someone who is just learning JavaScript.
