// Function to check if a given string is a palindrome using recursion function isPalindrome(str) { // Base case: if the string has 0 or 1 characters, it's a palindrome if (str.length <= 1) { return true; } // Check if the first and last characters are equal if (str[0] !=...
Another method to check if a string is a palindrome or not is by using aforloop. Below are the steps to check if a string is a palindrome in JavaScript. functionpalindromeFn(string){conststringLength=string.length;for(leti=0;i<stringLength/2;i++){if(string[i]!==string[stringLength-1...
Step 1: We have to find out if the given string is a palindrome or not. So to do this task we will create a function called isPalindrome and in this function, we will pass a parameter of string as str. So for this str, we will check the palindrome condition. Step 2: After the...

如果一个字符串忽略标点符号、大小写和空格,正着读和反着读一模一样,那么这个字符串就是palindrome(回文)。 注意你需要去掉字符串多余的标点符号和空格,然后把字符串转化成小写来验证此字符串是否为回文。 函数参数的值可以为"racecar",“RaceCar"和"race ......
if(string[i]!== string[len -1- i]){ return'It is not a palindrome'; } } return'It is a palindrome'; } // take input conststring =prompt('Enter a string: '); // call the function constvalue =checkPalindrome(string); console.log(value); ...
