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.
Last line is really interesting...
Function.prototype.apply.callWas not aware it works that way. Actually:
Function.prototype.call === Function.prototype.bind.call.apply.bind.callSo it seem that
Function.prototypefunctions (Function.prototype.bind,Function.prototype.call, etc.) do have object linkage toFunction.prototypeobject. We can even access such linkage. See here:Function.prototype.apply.__proto__ === Function.prototypeThat's why we can chain it deeply. Really interesting. Also was not aware of such Reflect feature. Thanks for sharing.
Thank you for your informative reply.
