if(a.some(a => a < 0 || a > 100)) return `вы ввели недопустимую оценку.`;

03

a = a.reduce((a,b)=> a + b) / a.length;

04

let i = 1;

05

for ( ; i < 6; i++) {

06

if(a >= (100 - 10 * i)) break;

07

}

08

return String.fromCharCode(64 + i)

09

I know what this code don’t correct(((

#6

Should onst be const?(I’m sure that’s just a matter of copy/paste!)

Aside. There’s nothing actually wrong with your code-it definitely performs the given task. It’s just that CC wants the exact text 'You have entered an invalid grade.' (in English), so if you just change the line where you say that in (Russian, is it?) to the English sentence, it should pass.
