// For this challenge you I'll be reversing a string.

// A simple way to reverse a string would be to create a new string and

// fill it with the characters from the original string, but backwards.

// To do this, we need to loop through the original string starting from the end,

// and every iteration of the loop we move to the previous character in the string

const FirstReverse = (str) => {

let newString = "";

// add each character to newString

for (var i = str.length - 1; i >= 0; i--) {

newString = newString + str.charAt(i);

}

return newString;

}

console.log(FirstReverse('Welcome'));

console.log(FirstReverse('raccar'));

//=============================================//

//============================================//

//Using the JavaScript in-built method

const FirstReverse = (str) => {

// first we split the string which creates an array of characters, e.g. ['c','a','t']

// then we call the reverse function on this array

// and finally we turn the reversed array back into a string using the join function

return str.split('').reverse().join('');

}

console.log(FirstReverse('Welcome'));

console.log(FirstReverse('raccar'));
