var demo = { counter : 5 ,getCounter: () => this.counter};
console.log(demo.getCounter())
will print undefined;
how Can it print 5 without modifying the code(means by using arrow function only)
I tried apply,bind function But Nothing works

`var demo = { counter : 5 ,getCounter: () => return demo.counter};`. The arrow function binds `this` to the scope in which `demo` is declared. – Ori Drori Oct 01 '18 at 19:22

1return is implicit with arrow functions without brackets – Sven Writes Code Oct 01 '18 at 19:23

@OriDrori but without modifying demo object. – Aditya kumar Oct 01 '18 at 19:23

@SvenWritesCode yes it was a mistake it should be var demo = { counter : 5 ,getCounter: () => this.counter}; – Aditya kumar Oct 01 '18 at 19:24

1@Adityakumar - without changing demo code? Override demo.getCounter after the object was declared. – Ori Drori Oct 01 '18 at 19:25
