JavaScript is an Object-Oriented Language, Object is the most important Role in JavaScript.
In JavaScript, almost "everything" is an object.
- Booleans can be objects (if defined with the
newkeyword) - Numbers can be objects (if defined with the
newkeyword) - Strings can be objects (if defined with the
newkeyword) - Dates are always objects
- Maths are always objects
- Regular expressions are always objects
- Arrays are always objects
- Functions are always objects
- Objects are always objects
All JavaScript values, except primitives, are objects.
Object values are written as name: value pairs (name and value separated by a colon).
Example of JavaScript Object:
let User= {
name : "username",
age : 25,
admin : false,
email:test@gmail.com
};
Object in 2 main things, one is key and the second is value.
in the above example, name, age, admin, and email are keys & username, 25, and test@gmail.com, false are valued.
Access object value:
we can access the value of the Object By key, If I need to Access the name of the user from the User object so, I can do,
var name = User.name or var name =User['name']
var name value is a username
