Language Feature

The following features supported by only ReoScript is non-compatible to ECMAScript/JavaScript standard.

More simpler inheriting based on prototype mechanism

This feature is planned to implement in v1.3

function A () {
  this.a = 10;
}

function B : A () {
  this.b = 20;
}

var b = new B;
console.log(b.a);

The output is:

10

Lambda Expression and Enhanced Collection Operations

var arr = [1, 5, 7, 8, 10, 13, 20, 24, 26];
var result = arr.where(n => n < 10).sum();

The result is:

21

• setTimeout and setInterval supported to pass arguments

  function check_alive(user) { if (...) { return 'ok'; } else { setTimeout(check_alive, 1000, user); } }

  var user = getCurrentUser(); setTimeout(check_alive, 1000, user);

• Binary literal supported (e.g. 0b1010)

  var num = 0b1010; console.log(num);

The output is:

10
