OBJECT IN JAVASCRIPT

Object:

*Objects contains information or data.

*Objects are variables that can Store both values and functions.

*JavaScript objects are collections of properties
Properties can be changed, added and deleted.

Example:

const car = {
  type: "Fiat",
  model: "500",
  color: "white"
};

type, model, and color are properties

"Fiat", "500", and "white" are property values

*Methods are actions that can be performed on objects.
Methods are functions stored as property values.

const person = {
  firstName: "John",
  lastName : "Doe",
  age      : 50,
  fullName : function() {
    return this.firstName + " " + this.lastName;
  }
};

Output: John Doe

Property Property Value
firstName John
lastName Doe
age 50
fullName function() {return this.firstName + " " + this.lastName;}

In an object method, this refers to the object.

In the example above, this refers to the person object.

I found the explanation of objects in JavaScript to be quite clear, especially the distinction between properties and methods. I've worked with objects in JavaScript for a while now, and I can attest to the fact that understanding how methods are functions stored as property values is crucial for effective object-oriented programming. One thing I've learned from my experience is that it's essential to be mindful of the context in which this is used, as it can sometimes lead to unexpected behavior if not properly understood. I'm curious, have you encountered any common pitfalls or gotchas when working with objects and methods in JavaScript, and if so, how do you avoid them?
