The main way you create a logger for your code. This will remove |

a log level, but it's replaced by this function: |

|
const disabled = () => {}; |
|

___BUG___: I'm not sure if modern compilers will remove this function or not. It |
|
|
|
|
does remove the log message from the output, so if you want to hide debugging infor |
|
|
|
|
spamming the console then that works. |
