The purpose of the prototype is to share properties and methods between objects that are created from the constructor function. For example, in our Person constructor function above, we added asayHellomethod to the prototype. This means that every object created from the Person constructor will hav...
When an arrow function is used to define a function, it does not have theprototypeattribute, so it cannot point to the constructor. const arrowFnc = () => {} console.log(arrowFnc.prototype) // undefined Regarding the difference between ordinary function and arrow function in the constructor,...
