Hmm, it doesn't look like every third letter was being removed before.. modulus is a great way to quickly single out every nth char.
function removeEveryThird(str) { const strArr = str.split(''); const newArr = []; strArr.forEach((char, index) => { if (index === 0 || index % 3 !== 0) { newArr.push(char); } }) console.log(newArr.join('')); return newArr.join(''); }
function removeEveryThird(str){var returnString = '';var words = str.split(' ');var counter = 0;for (var i = 0; i < words.length; i++){var word = words[i];counter = 0;for (var j = 0; j < word.length; j++){if (counter !== 3){returnString += word.charAt(j);}counter++;}- function removeEveryThird(str) {
- const strArr = str.split('');
- const newArr = [];
- strArr.forEach((char, index) => {
- if (index === 0 || index % 3 !== 0) {
- newArr.push(char);
- }
return returnString;- })
- console.log(newArr.join(''));
- return newArr.join('');
- }
