Tell us what’s happening:
Can anyone tell me why this isn’t working? My only suspicion is that the string created from my array doesn’t qualify as a repeated string. The function itself seems sound, as it runs the for loop [num] times and pushes it to [array], which I join( into a single string again. Feedback welcome, thanks!
Your code so far
let array=[];
function repeatStringNumTimes(str, num) {
// repeat after me
for (let i=0;i<num;i++){
array.push(str);
}
return array.join('');
}
console.log(repeatStringNumTimes("abc", 3));

Your code contains global variables that are changed each time the function is run. This means that after each test completes, subsequent tests start with the previous value. To fix this, make sure your function doesn’t change any global variables, and declare/assign variables within the function if they need to be changed.
Example:
var myGlobal = [1];
function returnGlobal(arg) {
myGlobal.push(arg);
return myGlobal;
} // unreliable - array gets longer each time the function is run
function returnLocal(arg) {
var myLocal = [1];
myLocal.push(arg);
return myLocal;
} // reliable - always returns an array of length 2
