let text = 'Hello world!';
let result = text.repeat(4);
console.log(result);var a="a";
var aaa=a.repeat(3); // "aaa"
// best implementation
repeatStr = (n, s) => s.repeat(n);setInterval(function(){
console.log("Hello");
console.log("World");
}, 2000); //repeat every 2sfunction repeatStringNumTimes(str, num) {
if (num < 1) {
return "";
} else {
return str + repeatStringNumTimes(str, num - 1);
}
}/* The string.repeat(n) method constructs and returns a new string
with "n" number of copies. */
const chorus = "Because I'm happy. ";
console.log(`Chorus lyrics: ${chorus.repeat(3)}`);
// → "Chorus lyrics: Because I'm happy. Because I'm happy. Because I'm happy. "
// Use within a function
greeting = (n, words) => words.repeat(n);
console.log(greeting(5, "howdy "));
// → "howdy howdy howdy howdy howdy "
