如果给定字符串以“Py”开头,则返回原始字符串。 functionstring_check(str1){if(str1 ===null|| str1 === undefined || str1.substring(0,2) === 'Py'){returnstr1; }return"Py"+str1; } console.log(string_check("Python")); console.log(string_check("thon")); 22.编写一个 JavaScript ...

2. Check Palindrome Write a JavaScript function that checks whether a passed string is a palindrome or not? A palindrome is word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run. Click me to see the solution ...
// Program to check if a word is a palindrome function isPalindrome(word) { // find the length of the word const length = word.length; // loop through half of the word for (let i = 0; i < length / 2; i++) { // check if first and last characters are the same if (word[...
1. Write a function to check if a given string is a palindrome. Hiring managers review how well a candidate can handle edge cases while handling case sensitivity, punctuation, and whitespace. This function takes a string as input to convert it into lowercase and then compares it with its rev...
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...
