What basics should a junior-frontend developer know about javascript?

Question

JavaScript

I'm going to an interview and I'm afraid that I won't be able to answer something using javascript. Please tell me what basics of JS junior you need to know in order to successfully pass an interview on js, and what questions are excusable for a junior at an interview if he does not answer them with an incentive that in the future he will gain experience in these technologies.

Answer 1

Everything is very conditional, in one company you can go to the middle in another, this is strong June, etc.
And of course there is no such list of questions, knowing the answers to which, you can be guaranteed to get a position. As a rule, these are standard questions on: closures, inheritance, something from OOP, promises, and some questions on js methods for working with data.
And as a rule, after js (if everything is ok) there is a transition to the main framework, which was emphasized before the interview.
And of course, these are even more unpredictable questions. So, despite all the hype headlines of course developers "frontend in 3 months" or "the threshold for entering the front is very low", it is not easy for a beginner to take the position of a junior.
