| ### Flags |
| |
| #### `--debug-arraybuffer-allocations` |

| |
| #### `--experimental-quic` |
| |
| Enable QUIC Protocol (under development) |
| |
| #### `--expose-internals` |

| Used for testing UDP functionality without attempting to send data. |
| |
| #### `--trace-promises` |
| |
| Enables tracing of promises for debugging and performance analysis. |
| |
| #### `--verify-base-objects` |
| |
| Allows verification of base objects for debugging purposes. |
