For those of you studying for interview I suggest getting the chatGPT app on your phone and talk to it. Say something like: " I will tell you the differences between null and undefined and you will tell me if I am correct". It helps you polishing your vocabulary, honing your communication skills and getting real-time feedback on your knowledge. Also , I mentioned this before but I repeat it: can't recommend enough Greatfrontend website to find the answers for the interview questions in javascript. The quizzes are free, no subscription required. It's a compilation of interview questions made by former Google engineers. Happy coding!
