JavaScript Basics: Reflect.apply

The method Reflect.apply is just a better and more meaningful way to do Function.prototype.apply. In other words, it allows you to call the given function using a specified context (this argument) on an array of arguments. Here is an example:

	let person = {
		name: "John",
		speak(city) {
			console.log(`Hi. I am ${this.name}. I am calling from ${city}.`);
		},
	};

	let someone = {
		name: "Jack",
	};

	person.speak("Houston");
	// Hi. I am John. I am calling from Houston.
	
	Reflect.apply(person.speak, someone, ["Boston"]);
	// Hi. I am Jack. I am calling from Boston.
	person.speak.apply(someone, ["Boston"]); // the same
	Function.prototype.apply.call(person.speak, someone, ["Boston"]); // the same

As I said in an earlier post, the Reflect object gathers all functionality related to reflection in one place. This makes it possible to write neater and more readable code.
