// Reversing a String in JavaScript.

// Approach1

function reverse(str) {

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

}

console.log(reverse("Namit"));

// Approach 2(Using ES6 syntax)

function reverse(str) {

return [...str].reverse().join("");

}

console.log(reverse("Namit"));

// Approach3(Without using in-built methods)

function reverse(str) {

let newString = "";

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

newString = newString + str[i];

}

return newString;

}

console.log(reverse("Namit"));

// Approach4(using recursion)

function reverse(str) {

if (str === "") {

return "";

}

return reverse(str.substr(1)) + str.charAt(0);

}

console.log(reverse("Namit"));

// Approach5(Using reduce function)

function reverse(str) {

return str.split("").reduce((acc, item) => item + acc, "");

}

console.log(reverse("Namit"));
