Is the code below correct? (Given that all the necessary imports are made)

Some routes are defined incorrectly because all routes need to have path prop

We need to render BrowserRouter around the whole app to connect the app to the browser's URL

The order of routes is wrong

The code is correct

Please, select when the subscription happens with the following code:

before every render

only once, on mounting phase, after completed render

only once, on mounting phase, before render

after completed render, only when props.source changes

after every completed render

before render, only when props.source changes

Is the component below defined correctly?

Please, select the correct statements regarding fixes/improvements that can be done with the component.

someProp should be placed in the dependency array

doSomething should be placed in the dependency array

everything is good

it is better to place the doSomething function inside of the effect

it is better to remove the second argument of the effect

We have the next component

Is there something that is wrong or can be improved in it?

Please, choose the correct options

we cannot write inline click handlers like this, we should define functions and then use them

Why this code does not work?

question sprint 2

We cannot use a loop to step through the elements of an array.

Break is only for switch statement

This code is correct

Variable i in block scope and we can`t see it after loop

What syntax were we emulating with this code?

a = a || 3;

b = b || 4;

[a, b] = [3, 4];

a = 3;

b = 4;

a = a && 3;

b = b && 4;

a = b = 3;
