DAX vs. M Language

What is DAX vs. M Language?
DAX and M serve different purposes in Power BI: M transforms and shapes data before it is loaded into the model, while DAX calculates values within the model itself, used for measures, calculated columns, and calculated tables. M operates on the whole table during a query or refresh, whereas DAX often calculates based on the current filter context in a report. Knowing which language applies to which stage avoids confusion when deciding where to solve a data problem.
