Fill Expression

Flow-Wing supports the fill keyword to create or update an array with a specific value.

Example Usage:

type Point = {
  x:int,
  y:int
}

var arr: Point[3] = [ 3 fill {x: 0, y: 0} ]

arr = [ 2 fill { x: 5 } ]

print(arr)

Output:

[{ x : 5, y : 0 }, { x : 5, y : 0 }, { x : 0, y : 0 }]

Note: If the fill count is less than the array size, remaining elements keep their old values. In the example above, [ 2 fill { x: 5 } ] overwrites only the first two elements; the third retains its previous value { x: 0, y: 0 }.
