Tests:

  • Object access

     
    let x = object.value;

  • Proxy access

     
    let x = proxy.value

  • Proxy with get handler access

     
    let x = proxyWithHandler.value

  • Use of simple getter

     
    let x = object.getData();

  • Use of defineProperty

     
    let x = object.dataProperty;

  • Proxy with get reflect handler access

     
    let x = proxyWithReflectHandler.value
