We are required to write a JavaScript function that takes in a string and a number, say n, and the function should return a new string in which all the letters of the original string are repeated n times.
For example: If the string is −
const str = 'how are you'
And the number n is 2
Then the output should be −
const output = 'hhooww aarree yyoouu'
Example
Following is the code −
const str = 'how are you';
const repeatNTimes = (str, n) => {
let res = '';
for(let i = 0; i < str.length; i++){
// using the String.prototype.repeat() function
res += str[i].repeat(n);
};
return res;
};
console.log(repeatNTimes(str, 2));Output
Following is the output in the console −
hhooww aarree yyoouu
