Palindrome

\n

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

\n

Example: radar, level, etc.

\n

Problem statement

\n

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

\n

Solution-1

\n
const palin = str => {\n  const reversedStr = str.split("").reverse().join("")\n\n  return str === reversedStr\n}\n\nconsole.log(palin("radar"))\n//true
\n

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

\n

Solution-2

\n
const palin = str => {\n  const strArray = str.split("")\n\n  return strArray.every((char, i) => {\n    return char === strArray[strArray.length - i - 1]\n  })\n}\n\nconsole.log(palin("radar"))\n// true
