Tell us what’s happening:

I know this isn’t the most elegant code in the world but it works in VSCode. Why not in here???

Your code so far

function toDecimal(binary) {
  power = 1;
  sum = 0;
  while (binary != "") {
    sum += (binary.substring(binary.length-1) * power)
    power *= 2;
    binary = binary.substring(0, binary.length-1);
  }
  return sum;
}

try calling the function and solve the errors that appear in the console

but the answer would be, because the environment you have in VSCode is not in strict mode
