Repeating letter string - JavaScript
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
