Script/program to check a string is palindrome or not: function testFun(txt){ var newTxt = txt.split(""); var myOP = ""; for(let i = newTxt.length-1; i>=0; i--){ console.log(newTxt[i]); myOP += newTxt[i]; } // console.log(myOP); if(txt === myOP){ console.log(txt + " is Palindrome"); }else{ console.log(txt + " is not Palindrome"); } } var str= "RAJU"; testFun(str); //First call of test function var str2= "MADAM"; testFun(str2); //Second call of test function Output: Raju is not Palindrome. //First call of test function MADAM is Palindrome.//Second call of test function
