Paul Tagliamonte c84c0b0fef return errors back to user (#4075)
* Log any Errors to stderr

This isn't perfect -- in fact, this is maybe not even very good at all,
but it's better than what we have today.

Currently, when we get an Erorr back from the WebSocket, we drop it in
kcl-lib. The web-app logs these to the console (I can't find my commit
doing that off the top of my head, but I remember doing it) -- so this
is some degree of partity.

This won't be very useful at all for wasm usage, but it will fix issues
with the zoo cli silently breaking with a "WebSocket Closed" error --
which is the same issue I was solving for in the desktop app too.

In the future perhaps this can be a real Error? I'm not totally sure
yet, since we can't align to the request-id, so we can't really tie it
to a specific call (yet).

map Apply a function to every element of a list. manual

Apply a function to every element of a list.

Given a list like [a, b, c], and a function like f, returns [f(a), f(b), f(c)]

map(array: [KclValue], map_fn: FunctionParam) -> [KclValue]

Arguments

Name Type Description Required
array [KclValue] Yes
map_fn FunctionParam Yes

Returns

[KclValue]

Examples

r = 10 // radius
fn drawCircle = (id) => {
  return startSketchOn("XY")
  |> circle({ center: [id * 2 * r, 0], radius: r }, %)
}

// Call `drawCircle`, passing in each element of the array.
// The outputs from each `drawCircle` form a new array,
// which is the return value from `map`.
circles = map([1, 2, 3], drawCircle)

Rendered example of map 0

r = 10 // radius
// Call `map`, using an anonymous function instead of a named one.
circles = map([1, 2, 3], (id) => {
  return startSketchOn("XY")
  |> circle({ center: [id * 2 * r, 0], radius: r }, %)
})
