Comments in Power Query
We can add comments to our code with single-line comments // or multi-line comments that begin with /* and end with */.
Example: Single-line comment
Power Query M
let //I am single line comment. MyTable = Table.FromRecords( { [CustomerID = 1, Name = "Ashish", Phone = "123-4567"], [CustomerID = 2, Name = "Katrina", Phone = "987-6543"], [CustomerID = 3, Name = "Alia", Phone = "543-7890"], [CustomerID = 4, Name = "Vicky", Phone = "676-8479"], [CustomerID = 5, Name = "Mohini", Phone = "574-8864"], [CustomerID = 6, Name = "Meenakshi", Phone = "574-8864"], [CustomerID = 7, Name = "Esha", Phone = "574-8864"], [CustomerID = 8, Name = "Anjali", Phone = "574-8864"] } ), Return = Table.ColumnCount(MyTable) in Return
Example: Multi-line comment
Power Query M
let /* I am multi-line comment*/ MyTable = Table.FromRecords( { [CustomerID = 1, Name = "Ashish", Phone = "123-4567"], [CustomerID = 2, Name = "Katrina", Phone = "987-6543"], [CustomerID = 3, Name = "Alia", Phone = "543-7890"], [CustomerID = 4, Name = "Vicky", Phone = "676-8479"], [CustomerID = 5, Name = "Mohini", Phone = "574-8864"], [CustomerID = 6, Name = "Meenakshi", Phone = "574-8864"], [CustomerID = 7, Name = "Esha", Phone = "574-8864"], [CustomerID = 8, Name = "Anjali", Phone = "574-8864"] } ), Return = Table.ColumnCount(MyTable) in Return
