 JavaScript interviews can be rough, even for developers with years of experience. You're expected to understand the language's basics and more complex parts. Interviewers want to see how well you know the language and how you use it to solve problems. It's a good idea to brush up on some common JavaScript interview questions before your interview.
 
 When preparing for a JavaScript interview, make sure you don't just memorize everything. Instead, focus on developing a good understanding of the language and getting to know it inside and out. Start by learning the basics, e.g., variables, and then you can move on to more advanced topics like async/await. Doing this will help you analyze things better and use your knowledge in building web apps.
