What are the ways of making objects in JavaScript?

Using Object Literal.

  const o = {
   name: "Mark",
   greeting() {
      return `Hi, I'm ${this.name}`;
   }
  };

  o.greeting(); //returns "Hi, I'm Mark"

Using Constructor Functions.

function Person(name) {
   this.name = name;
}

Person.prototype.greeting = function () {
   return `Hi, I'm ${this.name}`;
}

const mark = new Person("Mark");

mark.greeting(); //returns "Hi, I'm Mark"

Using Object.create method.

const n = {
   greeting() {
      return `Hi, I'm ${this.name}`;
   }
};

const o = Object.create(n); // sets the prototype of "o" to be "n"

o.name = "Mark";

console.log(o.greeting()); // logs "Hi, I'm Mark"
