❗arrow function as method❗️

🚧 under construction

JS ⟩ objects ⟩ arrow function ⟩ as method

⭐️ ❗️use with caution❗️

normally, you don't use arrow functions as methods, but if you have：

• an object A that has a method returning a new object B,

• object B has its own methods, you don't want this in these methods to refer to B, but refer to A instead,

then using arrow function as method is an option.

👉 see example： Sequence

💈範例

• Sequence - an iterable of numbers, whose iterator uses arrow functions as methods.
