const reverse = str => (str === '') ? '' : `${reverse(str.substr(1))}${str.charAt(0)}`;
// Example
reverse('hello world'); // 'dlrow olleh'.reverse javascript
const array1 = [1,2,3,4];
console.log('array1:', array1);
//"array1:" Array [1, 2, 3, 4]
const reversed = array1.reverse();
console.log('reversed:', reversed);
//"reversed:" Array [4, 3, 2, 1]
// Careful: reverse is destructive -- it changes the original array.
console.log('array1:', array1);
//"array1:" Array [4, 3, 2, 1]reverse string js
str.split('').reduce((reversed, character) =>{
return character + reversed;
