Binary Agents correct answer being denied

[ledoleo]

Hey guys, can you help me find out what is wrong with the code below?

I tried everything that I could think of and read other topics related with this challenge, but couldn’t find a satisfactory answer to why my code isn’t accepted even though it return the messages as expected.

function binaryAgent(str) {
  let arr = []
  arr = str.split(' ')
  str = ''
  arr.forEach(elem => {
    str += parseInt(elem, 2) + ' '
  })
  arr = str.split(' ')
  str = ''
  arr.forEach(elem => {
    str += String.fromCharCode(elem)
  })
  return str
}

Thanks!

Take a closer look at the arr after the second time str is split. There’s additional blank element at the end, which somehow makes into the result string.

Thank you! After your reply I’ve checked the arr after the first split and it’s returning

[
  '73',  '32',  '108', '111',
  '118', '101', '32',  '70',
  '114', '101', '101', '67',
  '111', '100', '101', '67',
  '97',  '109', '112', '33',
  ''
]

I have an empty string as the last position and it happened because I’ve concatenated a space at the end of parseInt…

It was something simple, but I really appreciate your help!
