Test code: 1 + 1. More code: 1 + {}.

Check out this function: (n : number) => n + 1

• ((x) => { var y = x + 42; return "abc"; })
• ((x) => { var y = x + 42; return "abc"; })(91)
• ((x : number) => { var y : number = x * 'a' ; return "abc"; })(1 + {})

Statements

class c1 {
  x = 42;
  f() {
    return [1,2,3].map(n => n + this.x );
  }
}
new c1().f();

class c {
  x = 42;
  name = "Fred";
  f()
  {
    return this.name + this.x;
  }
}
new c().f();

Together with syntax highlighting (highlight.js)

class c {
  x = 42;
  name = "Fred";
  f()
  {
    return this.name + this.x;
  }
}
new c().f();

function f(n: number) {
  return 42;
}
