Repeat a string

JavaScript
1

Tell us what’s happening:
the output is correct, but has “undefined” at the beginning of the string.
is there something wrong with my declaration?

Your code so far


function repeatStringNumTimes(str, num) {
  let myStr;
for (let i =0;i<num;i++){
myStr += str;
}
return myStr;
}

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

undefined is the starting value of myStr, it comes from there
