The requirement "Good / excellent knowledge of JS" to the jnu, what does the employer want to hear?

Question

JavaScript

In general, as an introduction to the requirements for today for front-end juniors, I decided to study the vacancies and came across the wording (in the requirements section) "Good knowledge of Js". So, what does the employer mean by these words, is good knowledge different from excellent? Is solving problems on codewars 5-6lv an elementary knowledge of the language or an average one (by Jun's standards)? Does this requirement include OOP, if so, do you need to understand the theory or already have several projects on OOP? Often (in 90% of vacancies) react / vue is mentioned in the requirements, it was always thought that knowledge of the framework is already almost a middle position, but the market decides that juniors should also know react / vue, but what level should it be? I understand that until you pass the interview yourself, you will not know

Answer 1

The employer probably needs the employee to cope with simple work tasks in JS on their own. And I didn't have to redo it.
Simple ones are not writing a SPA from scratch in React / Vue, but maybe making a minimal edit or screwing a plugin to the front.
The candidate, believing that “I know JS well”, rather exaggerated conceit and simply does not know what he does not know yet.
So, if you strongly doubt that you know JS well, but at the same time you are able to roughly figure out and understand in someone else’s front code what which section does, feel free to respond to the vacancy.

Answer 2

This is a subjective assessment of the employer. Anything can be here: from “I can basically do it” to “I know how V8 works from the inside”

Answer 3

Please the signorista eccentrics with the knowledge of Japanese crutches. No wonder they were looking for these puzzles on the Internet. Or better yet, don't go there. All interviews are basically about the fact that a person is not a frostbitten moron, technicians check that they know something, the director, based on the opinion of hr and technicians, interviews the candidate and gives the go-ahead.
