Benchmark: if else vs runtime polymorphic

Script Preparation code:

class Base {
  foo () {}
}

class A extends Base {
  foo () {}
}

class B extends Base {
  foo () {}
}

var a = new A()
var b = new B()

function a_foo () {}
function b_foo () {}

var type = 'componenta'

Tests:

if else
if (type === 'componenta') { a_foo() }
polymorphic
a.foo()
a_foo
a_foo()
