Apply a function to every element of a list.
map(
@array: [any],
f: fn(any): any,
): [any]
Given a list like [a, b, c], and a function like f, returns
[f(a), f(b), f(c)]
Arguments
| Name | Type | Description | Required |
|---|---|---|---|
array | [any] | Input array. The output array is this input array, but every element has had the function f run on it. | Yes |
f | fn(any): any | A function. The output array is just the input array, but f has been run on every item. | Yes |
Returns
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..3],
f = drawCircle
)
r = 10 // radius
// Call `map`, using an anonymous function instead of a named one.
circles = map(
[1..3],
f = fn(@id) {
return startSketchOn(XY)
|> circle( center= [id * 2 * r, 0], radius= r)
}
)
