Answer 1

To comment in power query m in POWER BI

It will supports  two different types of comments:

i) Single line comments can be started with //

ii) You can comment out multiple lines or comment out text in the middle of a line using /* 

Examples

*/ (e.g. = 5 + /* any comments */ 1)

 

It might seem to disappear in the formula bar if they are at the end of the line, but they are still there.
