Fibonacci ES6 Generator

fibonacci-generator.js

function *fibonacci(n) {
  const infinite = !n && n !== 0;
  let current = 0;
  let next = 1;
  
  while (infinite || n--) {
    yield current;
    [current, next] = [next, current + next];
  }
}

recursive-fibonacci-generator.js

function *fibonacci(n = null, current = 0, next = 1) {
  if (n === 0) {
    return current;
  }

  let m = n !== null ? n - 1 : null;

  yield current;
  yield *fibonacci(m, next, current + next);
}

usage.js

let [...first10] = fibonacci(10);
console.log(first10);
// [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]

I really like your code and I'd like to know if you can explain your thought process on it. My code is a bit different. I would appreciate some advice. Thanks!

function fibonacciGenerator (n) {
var output = [];
if (n === 1) {
output = [0];
}
else if (n === 2) {
output = [0, 1];
}
else {
output = [0,1];
for (var i = 2; i < n;i++) {
output.push(output[output.length - 2] + output[output.length - 1]);
}
}
return output;
}
var output = fibonacciGenerator(10);
console.log(output);

var fibonacci_series = function (n)
{
if (n===1)
{
return [0, 1];
}
else
{
var s = fibonacci_series(n - 1);
s.push(s[s.length - 1] + s[s.length - 2]);
return s;
}
};

console.log(fibonacci_series(5));
