What is the use of javascript Object and how we can define them?

Answer 1

Variables are used to hold data. Objects are kind of similar but they can hold more data. Think of a variable as the little spice container and an object as a spice rack (at least that is how I picture it). If you wanted to create a character, for example, you would define a variable to hold name, age, profession, etc. An object can hold all that information in form of a list in one container. It makes your code more succinct and easy to read.

An example of an object:

var account = {
name: "checking",
currentBalance: 185,
minBalance: 25,
owner: "Vipul"
};
