Tell us what’s happening:
convertToInteger(“10011”) should return 19
convertToInteger(“111001”) should return 57
How to return 19, 57?
I don’t understand.

Your code so far


function convertToInteger(str) {
  return parseInt(str);
  
}

convertToInteger("10011");

parseInt needs a second parameter, take a look at the documentation:

parseInt(string, radix);

function convertToInteger(str) {
var a = parseInt(str);
if(isNaN(parseInt)) {return 0}
return parseInt * 100;
}

convertToInteger(“10011”);

question:
convertToInteger(“10011”) should return 19
convertToInteger(“111001”) should return 57
convertToInteger(“JamesBond”) should return NaN

if enter console.log(converToIntger(parseInt));can sumbit??

You don’t need all those things, parseInt() itself returns NaN if the thing passed is not a number

And you don’t need to multiply by 100 - the number from parseInt is already the number you need
