Basic Algorithm Scripting: Repeat a String Repeat a String Repeat a given string str (first argument) for num times (second argument). Return an empty string if num is not a positive number.
Remember to use Read-Search-Ask if you get stuck. Write your own code. repeatStringNumTimes("", 3) should return "". Passed repeatStringNumTimes("abc", 3) should return "abcabcabc". Passed repeatStringNumTimes("abc", 4) should return "abcabcabcabc". Passed repeatStringNumTimes("abc", 1) should return "abc". Passed repeatStringNumTimes("", 8) should return "*******". Passed repeatStringNumTimes("abc", -2) should return "". Passed The built-in repeat()-method should not be used /////////////////////////////////////////////////////// function repeatStringNumTimes(str, num) { // repeat after me let empty=""; let text=[]; if(num > 0){ return text.substr(0, num)===num; }else{ return text + empty; } } repeatStringNumTimes("abc", -2);
