Palindrome

A word or sentence that reads the same backward or forward.

Example: radar, level, etc.

Problem statement

Write a function that accepts a string as an argument and returns true, if the string is a palindrome and returns false, if otherwise.

Solution-1

const palin = str => {
  const reversedStr = str.split("").reverse().join("")

  return str === reversedStr
}

console.log(palin("radar"))
//true

In the code snippet above, on line 2, we are reversing the string received as an argument.

Solution-2

const palin = str => {
  const strArray = str.split("")

  return strArray.every((char, i) => {
    return char === strArray[strArray.length - i - 1]
  })
}

console.log(palin("radar"))
// true
