| The trick is called *method borrowing*. | ||
|
|
||
| We take (borrow) a join method from a regular array `[].join`. And use `[].join.call` to run it in the context of `arguments`. | ||
|
|
||
| Why does it work? | ||
|
|
||
| That's because the internal algorithm of the native method `arr.join(glue)` is very simple. | ||
|
|
||
| Taken from the specification almost "as-is": | ||
| 위와 같은 방법을 *메서드 빌리기(method borrowing)* 라고 합니다. | ||
|
|
||
| 1. Let `glue` be the first argument or, if no arguments, then a comma `","`. | ||
| 2. Let `result` be an empty string. | ||
| 3. Append `this[0]` to `result`. | ||
| 4. Append `glue` and `this[1]`. | ||
| 5. Append `glue` and `this[2]`. | ||
| 6. ...Do so until `this.length` items are glued. | ||
| 7. Return `result`. |
