JS Loops about javascript HOT 12 CLOSED

while learning JS, i ran into a small issue and im stuck . Any help rendered would be appreciated

Hi ,In the for loop ,both initial and final value of i is inclusive:
for(let i=5;i<=10;i++)
due to which **loop runs 6 times ** i think that might be the issue .Hope it helps.

Hello, it still doesn't give me the required answer
Thanks for the help though

still didnt work for me

Hi @dree-max, there's a super easy approach without loops if you want to... i.e. using .repeat().

You can simply solve this in 4 lines of code:

function scream(n) {
    let str = 'a'.repeat(n)
    console.log(str)
}

scream(10) 

Lemme know if you have any questions. Cheers :)

Unfortunately this one has to have loops because it's what's been examined in this particular exercise!
Thank you for the other option though I tried it out and it works just fine

from javascript.

You can do it like this!

function scream(n)
{
    let str = '';
    while(n--)
    {
        str +='a';
    }
    console.log(str);
}

scream(10);

from javascript.

Hello @ dree-max, you have already figured that out but still useful to give my two cents.

In Pseudocode, that problem would be solved like this:

 n = 5
 i = 0
 from i to n:
     //  do

In JavaScript, that would be solved like this:

function scream(n) {
     let str = "";
     for (let i = 0; i<n; i++) 
          str = str + 'a';
     return str;
}

console.log(scream(2)); // aa
console.log(scream(5)); // aaaaa

from javascript.

@dree-max run loop as i=0 ; i < n; i++
this have to work

from javascript.

function scream(n) {
let str = "";
for (let i = 0; i<n; i++)
str = str + 'a';
return str;
}

console.log(scream(3)); // aaa
console.log(scream(5)); // aaaaa

//This will solve the issue.
Happy to help :)

from javascript.

function scream(n) {
return Array(n+1).join('a');
}

console.log(scream(3)); // aaa
console.log(scream(5)); // aaaaa

Hey @dree-max , Easy approach without loops if you want to..(using an Array and then join it with 'a' as the separator.)

from javascript.

// simple solution with for loop

`function scream(n) {
let str = '';
for (let i = 0; i < n; ++i) {
str += 'a';
}

return str;
}

console.log(scream(5));
console.log(scream(10));`
