Could someone explain me how this code works line to line? Thanks.

function func(str){ var len=str.length; for(var i=0;i<Math.floor(len/2);i++){ if (str[i]!==str[len-1-i]) return false; } return true; }

That function check if a string is palindrome (a string is palindrome if its equal if readed to contrary like "baninab") Now line by line: - get string length - for any n-th element (character) check if its equals to last nth element, while half string is checked - if they are different return false (string is not palidndrome) - if function has not returned from loop mean that string is palindrome then return true
