What do they ask for an interview for a javascript developer (Junior/Trainee)?

Question

JavaScript

Good afternoon.
I work as a layout designer in a small town (400k) in a subsidiary office, head office in Moscow time.
Slowly I studied js, mainly learnjavascript and YouTube.
In early April, our own js developer from Moscow will interview me to just check my knowledge, since there is no question of hiring, rather they will simply increase the bonus and just check whether I am apparently growing in skill or not I do
n’t want to lose face And still there is 2 weeks, to strenuously something to repeat.
The question is, what can js junior ask?
No one will rape me, because everyone understands that I came to the layout without experience, but still.

Answer 1

Layout + js + Junior = good command of Jquery in 90% of cases.
Optional: be able to write your own Jquery function and your own Jquery plugin.
That is, you should work with him as freely as possible.
If we talk about "pure" js (in addition to queues, arrays, recursions, sorting): be able to correctly create the desired class and use it. Everything that is more complex in architecture is already higher than Junior'a.
It is best if you prepare for the interview a couple of js files that simplify the development of js files (a function, or your own library, or a Jquery plugin, etc.), which you can use in future work repeatedly and show these developments on github ( well, about DEMO - also do not forget to do it).

Answer 2

I recently went through 5 interviews. Questions that were repeated more than once:

• good old closure
  
• event bubbling and how you can benefit from it
  
• difference between Function#bind, Function#apply and Function#call
  
• difference between arrow function and regular function
  
• write to FizzBuzz
  

Answer 3

closures
callbacks
fetch
class
promise
event
And I advise you to switch from jquery to vuejs or react in the long run.
Watch this introductory video and it will become clear why you need to take vue or react instead of jquery if you plan to develop as a javascript programmer.

Answer 4

There are 2 courses on JS on YouTube, from Zoraks and JavaScript Weird Parts. Listen three times in a circle and learn everything that they give there, this is a direct base-base. These two video courses are great to enlighten in terms of JS. Then polish on top with chips from ES6+. It would also be very good to solve a hundred problems on algorithms and data structures in order to develop automatism, because. one language is not enough, you still need to be able and able to hammer nails with it ...

Answer 5

base and will study and understand the different methods.

Answer 6

Repeat how to work with arrays, objects (sort, filter, etc.). How to work with http requests, how closure works
