How to reverse a string in JavaScript
Method 1: Use the build-in functions: split, reverse and join
function reverse(str) {
return str.split('').reverse().join('');
}
Method 2: Use the for loop
function reverse(str) {
let res = '';
for (let i = str.length - 1; i >= 0; i--) {
res += str[i];
}
return res;
}
