Pipes (|>)

The pipe operator passes the left value into the next function call.

Basic usage

result = value |> transform() |> normalize();

Async pipe stage

items = items
  |> await list.filter((x) => x > 1)
  |> list.map((x) => x * 2);

When to use it

Pipes make chained transformations easier to read than nested calls.
