Exploring the arguments array

Regular functions, like sayHiAlt, are going to have an arguments array that's accessible inside of the function:

var user = {  name: 'Andrew',  sayHi: () => {    console.log(`Hi. I'm ${this.name}`);  },  sayHiAlt() {    console.log(arguments);    console.log(`Hi. I'm ${this.name}`);  }};user.sayHiAlt();

Now, it's not an actual array, it's more like an object with array; like properties, but the arguments object is indeed specified in a regular function. If I pass in one, two, and three and save the file, we'll get that back when we log out arguments:

var user = {  name: 'Andrew',  sayHi: () => {    console.log(`Hi. I'm ${this.name}`);  },  sayHiAlt() {    console.log(arguments);    console.log(`Hi. I'm ${this.name}`);  }};user.sayHiAlt(1, ...
