const univer = new Univer({ logLevel: LogLevel.WARN })
```

| Value     | Number | Enabled messages                    |
| --------- | ------ | ----------------------------------- |
| `SILENT`  | 0      | None                                |
| `ERROR`   | 1      | Errors                              |
| `WARN`    | 2      | Warnings and errors                 |
| `INFO`    | 3      | Information, warnings and errors    |
| `VERBOSE` | 4      | Debug messages and all levels above |

`new Univer()` uses `INFO` by default; `createUniver()` uses `WARN` unless overridden.
