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!
