There is an difference between

count ++ vs ++ count

Count++ increment the value but only from the next line changes are applicable

++Count increment the value but the changes are applicable immediately.
Count = 5

Example
Return Count ++
Console.log(count)
// 5
// 6

return ++count
Console.log(count)

// 6
// 6

You could have created an object and created an increment key and assign arrow function to it
And return the whole object counter

Return obj {
Increment: () =>{
Return ++ count
}



}

solved this hours ago, here just for your explanation

[KyuriousBot]

we have already assigned init to count in the first line: let count = init;
why are we doing count = init again in the reset function body? When I try to return count directly, it outputs wrong answer.

i think the problem in the description attached is a different one !
