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

Question

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;
}

Answer 1

I am asking only if I can't understand how exactly the code works. I am still begginer in Javascript :-).

Answer 2

4th time you are asking approx samiler (Code changed) question.

Answer 3

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
