Palindrome finding problem | Task 1 in JavaScript

Question is to finding the palindrome words in the array


                let arr = ["Mango", "Orange", "Banana", "Pineapple", "Noon", "Day", "Night", "Morning"];

Feel free to use dev tools console tab after seeing the methods you can find the palindrome words there


                Palindrome word is identified in methods, Noon

Method 1

Using for loop only to findout


                for (let i = 0; i < arr.length; i++) {
                let singleWord = arr[i];
                let reversedWord = "";

                for (let j = 0; j < singleWord.length; j++) {
                reversedWord = singleWord[j].toLocaleLowerCase() + reversedWord;
                }

                if (reversedWord === singleWord.toLocaleLowerCase()) {
                console.log('Palindrome word is identified in method 1,' + singleWord);
                }
                }

Method 2

Using string methods to split, reverse and join the words


                for (let i = 0; i < arr.length; i++) {
                let singleWord = arr[i];
                let reversedWord = singleWord.toLocaleLowerCase().split("").reverse().join().replaceAll(',', '');

                if (reversedWord === singleWord.toLocaleLowerCase()) {
                console.log('Palindrome word is identified in method 2,' + singleWord);
                }
                }

Method 3

Using while loop with a condition and using for...of loop for char in string


                let i = 0;
                while (i < arr.length) {
                let singleWord = arr[i];

                 let reversedWord = "";
                for (let char of singleWord) {
                reversedWord = char.toLocaleLowerCase() + reversedWord;
                }

                if (reversedWord === singleWord.toLocaleLowerCase()) {
                console.log('Palindrome word is identified in method 3,' + singleWord);
                }

                i++;
                }
