Context of arrow function in Node.js

Question

Consider the following example:

const f1 = () => this;

function f2() {
    return this;
}

console.log(f1(), f2());

When this code is executed in a browser, the result is as follows:

> window window

But when this code is executed in Node.js, the result is not quite as expected:

> {} global

Why in Node.js the empty object was taken as the context of an arrow function instead of Global Object (global on this platform)?

In nodejs, when you use arrow operator, the this operator won't contain the reference object by nature....thatswhy if we wanted to refer any variables using 'this' , we avoid using arrow operators in function definition.

Therefore in your case this is the reason why it's printing empty object.
