code :

3.1 Variables and Data Types

Variables are used to store and manipulate data in JavaScript. Here are the key concepts related to variables and data types:



3.1.1 Variable Declaration and Assignment

- Use the `let` keyword to declare a variable that can be reassigned later.

- Use the `const` keyword to declare a constant variable that cannot be reassigned.

- Example:

javascript

let name = "John";

const age = 25;

3.1.2 Data Types

JavaScript has several built-in data types, including:

- Numbers: Numeric values, such as `3`, `3.14`, or `1000`.

- Strings: Textual values enclosed in quotes, such as `"Hello"` or `'World'`.

- Booleans: Logical values `true` or `false`.

- Arrays: Ordered lists of values, enclosed in square brackets, such as `[1, 2, 3]`.

- Objects: Key-value pairs enclosed in curly brackets, such as `{ name: "John", age: 25 }`.

- Null: Represents the absence of any object value.

- Undefined: Represents an uninitialized variable.



3.2 Operators and Expressions

Operators allow you to perform operations on variables and values. Here are some commonly used operators:



3.2.1 Arithmetic Operators

- Addition: `+`

- Subtraction: `-`

- Multiplication: `*`

- Division: `/`

- Modulus (Remainder): `%`

- Example:

javascript

let x = 10;

let y = 5;

let sum = x + y; // 15

let product = x * y; // 50

3.2.2 Comparison Operators

- Equal to: `==`

- Not equal to: `!=`

- Greater than: `>`

- Less than: `<`

- Greater than or equal to: `>=`

- Less than or equal to: `<=`

- Example:

javascript

let a = 10;

let b = 5;

console.log(a > b); // true

console.log(a == b); // false

3.2.3 Logical Operators

- AND: `&&`

- OR: `||`

- NOT: `!`

- Example:

javascript

let sunny = true;

let warm = true;

console.log(sunny && warm); // true

console.log(sunny || warm); // true

console.log(!sunny); // false

3.3 Control Flow and Conditional Statements

Conditional statements allow you to control the flow of execution based on certain conditions. Here are two commonly used conditional statements:



3.3.1 If Statement

- Executes a block of code if a specified condition is true.

- Example:

javascript

let hour = 12;

if (hour < 12) {

console.log("Good morning!");

} else {

console.log("Good afternoon!");

}

3.3.2 Switch Statement

- Evaluates an expression and executes different code blocks based on different cases.
- Example:

javascript
let day = "Monday";
switch (day) {
case "Monday":
console.log("Start of the week");
break;
case "Friday":
console.log("End of the week");
break;
default:
console.log("Some other day");
}
3.4 Functions
Functions allow you to group and reuse blocks of code. Here's an example of defining and calling a function:
javascript
function greet(name) {
console.log("Hello, " + name + "!");
}
greet("John"); // Hello, John!
3.5 Arrays and Objects
Arrays and objects are used to store and manipulate collections of data.
3.5.1 Arrays
- Arrays store multiple values in a single variable.
- Example:
javascript
let numbers = [1, 2, 3, 4];
console.log(numbers[0]); // 1
3.5.2 Objects
- Objects store key-value pairs.
- Example:
javascript
let person = {
name: "John",
age: 25,
city: "New York"
};
console.log(person.name); // John
Summary:
- Variables are used to store and manipulate data in JavaScript.
- JavaScript has various data types, including numbers, strings, booleans, arrays, and objects.
- Operators and expressions allow you to perform operations on variables and values.
- Conditional statements like `if` and `switch` control the flow of execution based on conditions.
- Functions allow you to group and reuse blocks of code.
- Arrays and objects are used to store and manipulate collections of data.
Homework:
- Practice writing JavaScript code that uses variables, data types, operators, conditional statements, and functions.
