| Order | Scripts with `async` execute *in the load-first order*. Their document order doesn't matter -- which loads first runs first. | Scripts with `defer` always execute *in the document order* (as they go in the document). |

| `DOMContentLoaded` | Scripts with `async` may load and execute *before `DOMContentLoaded`*: if they are small, and the document is big, they load faster. | Scripts with `defer` always execute *after `DOMContentLoaded`*: they wait for it if needed. |

| `DOMContentLoaded` | Scripts with `async` may load and execute while the document has not yet been fully downloaded. | Scripts with `defer` execute after the document is loaded and parsed (they wait if needed), right before `DOMContentLoaded`. |
