Property Access

Static property access

Binding to Getter/Setter using bs.get, bs.set.

This attribute helps get and set the property of a JavaScript object.

RE
type textarea;
[@bs.set] external set_name: (textarea, string) => unit = "name";
[@bs.get] external get_name: textarea => string = "name";

Dynamic property access

Binding to dynamic property access/set using bs.set_index, bs.get_index

Input:

RE
type t;
[@bs.new] external create: int => t = "Int32Array";
[@bs.get_index] external get: (t, int) => int = "";
[@bs.set_index] external set: (t, int, int) => unit = "";
let i32arr = create(3);
i32arr->set(0, 42);
Js.log(i32arr->get(0));

Output:

JS
var i32arr = new Int32Array(3);
i32arr[0] = 42;
console.log(i32arr[0]);
