The Object class represents one of JavaScript's data types. It's used to store keyed collections as well as more complex entities
2. How can you Create a JavaScript Object?
With JavaScript, you can define and create your objects.
There are different ways to create new objects:
1. Create a single object, using an object literal.
2. Create a single object, with the keyword new.
Using an Object Literal:
This is the easiest way to create a JavaScript Object.
Using an object literal, you both define and create an object in one statement.
An object literal is a list of name: value pairs (like name: "mujeeb") inside curly braces {}.
Example:
Using new keyword.
Example:
Using Object.create().
Example:
Accessing Properties of an Object.
The syntax for accessing the property of an object is:
Object Methods: 1. Keys. 2. values. 3. delete. 4. freeze. 1. keys:
The Object.keys() method produces an array of enumerable property names for a given object, iterated in the same way as a normal loop.
Example:
2. values:
The Object.values() method returns an array of enumerable property values for a given object in the same order as a for...in loop.
Example:
3. delete:
This method will remove the whole property from an array.
Example:
4. freeze:
An object is frozen using the Object.freeze() method. An object that has been frozen cannot be changed; Object.freeze() returns the same object that was passed in as an argument.
