Your code so far


function convertHTML(str) {
  // :)
  let charCode = {
    "&" : "&​amp;",
    "<" : "&​lt;",
    ">" : "&​gt;",
    "'" : "&​quot;",
    "\"" : "&​apos;"
  }
  return str.split('').map(e => e in charCode ? charCode[e] : e).join('')
}

convertHTML("Dolce & Gabbana");

You have hidden characters (\u200b Zero-width space), between “&” and the rest of the entity strings (from copy/paste). If you paste the code into the console on Chrome, they will show up as a red dot. You can also hover over them to see what it is.
