Step 1: Understanding Objects:
An object is a complex data type that allows you to store and organize data in a structured way. It is a collection of key-value pairs, where each key is a string and each value can be any data type, including other objects.
Step 2: Creating Objects:
You can create an object using curly braces {}. Here’s a simple example:
This creates an empty object named is “car”
Step 3: Adding Properties:
You can add properties to an object using the dot notation or square bracket notation:
for example:
Dot Notation:
Square Bracket Notation:
Both approaches achieve the same result: adding properties to the “car” object.
Step 4: Accessing Properties:
You can access the properties of an object using dot notation or square bracket notation:
Step 5: Objects with Functions (Methods)
Properties in an object can also hold functions, and these are referred to as methods.
for example:
Step 6: Nested Objects:
Objects can contain other objects, creating a nested structure:
output:–
Step 7: Removing Properties:
You can remove a property from an object using the delete keyword:
Step 8: Object Methods:
JavaScript provides built-in methods for working with objects.
For example:
- Object.keys(obj): Returns an array of a given object’s own property names.
- Object.values(obj): Returns an array of a given object’s own property values.
- Object.entries(obj): Returns an array of a given object’s own key-value pairs as.
