Understanding the M Language Syntax
M is a strong and expressive question language that’s used to create information transformations in Energy Question. It’s primarily based on the F# programming language and it shares a lot of its options, together with its use of sorts, capabilities, and expressions.
The M language is split into two important components: the expression syntax and the assertion syntax. The expression syntax is used to create values, whereas the assertion syntax is used to carry out actions.
The next desk offers a abstract of the primary parts of the M language syntax:
| Component | Description |
|---|---|

| Syntax | Description |
|---|---|
| perform (parameter1, parameter2, …) { | Defines the start of the perform. |
| statements | Comprises the code that defines the perform’s logic. |
| return worth | Specifies the worth that the perform returns. |
| } | Defines the top of the perform. |
As soon as a customized perform has been created, it may be used within the question by calling it with the suitable parameters. Expressions will be created immediately within the Superior Editor utilizing the usual syntax for the Energy Question Formulation Language (M).
