Fat-arrow functions, also known as arrow functions, are a concise way to write function expressions in JavaScript. One of their defining characteristics is how they handle the `this` context. Unlike regular functions, which bind their own `this` to the object they are called on, arrow functions do not have their own `this` binding. Instead, they lexically capture the `this` value from their surrounding context at the time they are defined.

This means that when an arrow function is used as a method in an object, it does not refer to the object itself when invoked, which can lead to issues if you are trying to access properties of that object using `this`. In contexts where you need to refer to the object that owns the method, using an arrow function is not appropriate.

For instance, if you have an object with a method defined as an arrow function and you try to call that method, the `this` inside the arrow function would refer to the scope in which the method was defined, not the object itself. This is why using arrow functions as methods is generally discouraged; they do not behave as expected in terms of object-oriented programming and the concept of `this`.

Thus, the understanding that arrow functions do not bind
