Repeat a String Repeat a String - Basic Algorithm Scripting - Free Code Camp

In this basic algorithm scripting tutorial we do an exercise called "repeat a string repeat a string". This is another tutorial that makes up a series where I cover the FreeCodeCamp curriculum. Enjoy!

Hello Sir Useful Programmer, how are you?
I watched your video and simplified a code a little:
function repeatStringNumTimes(str, num) {
let result = "";
for(let i = 1; i <= num; i++){
result = str + result;
}
return result;
}
setting i=1 eliminates need for use of if statement.
It was a tough challenge and I have not done it for long time. Thing has settled in my mind and all the videos I watched over and over made me doing it straight away LOL. Anyway, thank you for your hard work, I watch your new productions, although that stuff is well above my level. I am now working full time as warehouse operative, so not much time for coding... It never was, as I was looking after my son during lockdown... I have lost all the weight I gained during unemployment though;) All the best!

Thank you for the videos. Thanks to them I's able to resolve mi first challenge without hint or help.

I used this and it worked too;

let result = ""
for (let i = num; i > 0; i--) {
result += str
}
return result
}

I've been enjoying your videos and explanations, thanks for all you've done.

Thank you Mr. Ian I even tested it out on my own by having it repeat RRT 3 times in a row and RRT stands for Registered Respiratory Therapist.
function repeatStringNumTimes(str, num) {
if (num <= 0) {
return "";
}

let result = "";

for (let i = 0; i < num; i += 1) {
result += str;
}

return result;
}

console.log(repeatStringNumTimes("abc", 3));

With these challenges really not knowing how to start them could I give me some advice how u know what to start with and what to write

[jakubzomerfeld]

The newest approach is to use native "repeat" function, ex:

"abc".repeat(3) //abcabcabc

[alvirfrancisco]

here's mine. ez

let newstring = ""
for (let i =0; i < num; i++){
newstring += str
}
return newstring;
}

[falafel]

let result="";
while(num>0){
num--;
result+=str;
}
return result;

Thanks a lot :)
Mine was...
function repeatStringNumTimes(str,  num) {
  let returnString = '';


  }

  return returnString;
}

repeatStringNumTimes("abc",  3);
