3. JavaScript Basics for the 98-382 Exam
What is JavaScript?
JavaScript is a scripting language used to create dynamic and interactive web pages. Unlike HTML (which structures content) and CSS (which styles content), JavaScript adds behavior to web pages.
How to Include JavaScript in HTML
JavaScript can be added to HTML in three ways:
1. Inline Scripting
```html
<button onclick="alert('Hello!')">Click Me</button>
2. Internal Scripting
```html
<script>
console.log("This is internal JavaScript");
</script>
3. External Scripting
```html
<script src="script.js"></script>
Basic Syntax Rules
- JavaScript is case-sensitive.
- Statements end with a semicolon (`;`).
- Comments are written with `//` (single-line) or `/ /` (multi-line).
4. Variables and Data Types in JavaScript
Declaring Variables
JavaScript variables can be declared using:
- `var` (function-scoped, older syntax)
- `let` (block-scoped, modern syntax)
- `const` (block-scoped, cannot be reassigned)
Example:
```javascript
let age = 25;
const PI = 3.14;
var name = "John";
Data Types
JavaScript has primitive and object data types:
| Primitive Types | Description |
| `number` | Integers and decimals (`5`, `3.14`) |
| `string` | Text (`"Hello"`) |
| `boolean` | `true` or `false` |
| `null` | Intentional absence of value |
| `undefined` | Variable declared but not assigned |
| `symbol` | Unique identifier (ES6) |
Example:
Javascript
let score = 100; // number
let greeting = "Hello"; // string
let isPassed = true; // boolean
let empty = null; // null
5. Operators and Expressions
Arithmetic Operators
- `+` (Addition)
- `-` (Subtraction)
- `` (Multiplication)
- `/` (Division)
- `%` (Modulus)
Example:
```javascript
let x = 10 + 5; // 15
let y = 20 % 3; // 2 (remainder)
Comparison Operators
- `==` (Loose equality)
- `===` (Strict equality)
- `!=` (Not equal)
- `!==` (Strict not equal)
- `>` (Greater than)
- `<` (Less than)
Example:
```javascript
5 == "5"; // true (loose equality)
5 === "5"; // false (strict equality)
Logical Operators
- `&&` (AND)
- `||` (OR)
- `!` (NOT)
Example:
```javascript
if (age > 18 && hasLicense) {
console.log("Can drive");
}
6. Control Flow and Loops
Conditional Statements
- `if-else`
```javascript
if (score >= 70) {
console.log("Passed");
} else {
console.log("Failed");
}
- `switch`
```javascript
switch(day) {
case "Monday":
console.log("Weekday");
break;
default:
console.log("Weekend");
}
Loops
- `for` Loop
```javascript
for (let i = 0; i < 5; i++) {
console.log(i); // 0,1,2,3,4
}
`while` Loop
```javascript
let i = 0;
while (i < 5) {
console.log(i);
i++;
}
7. Functions and Scope
Function Declaration
```javascript
function greet(name) {
return "Hello, " + name;
}
console.log(greet("Alice")); // "Hello, Alice"
Arrow Functions (ES6)
```javascript
const add = (a, b) => a + b;
console.log(add(2, 3)); // 5
Scope (Global vs. Local)
- Global Scope: Variables declared outside functions.
- Local Scope: Variables declared inside functions.
Example:
```javascript
let globalVar = "I'm global";
function testScope() {
let localVar = "I'm local";
console.log(globalVar); // Works
}
console.log(localVar); // Error (not defined)
8. Arrays and Objects
Arrays
```javascript
let fruits = ["Apple", "Banana", "Orange"];
console.log(fruits[1]); // "Banana"
Objects
```javascript
let person = {
name: "John",
age: 30,
isStudent: false
};
console.log(person.name); // "John"
9. Error Handling and Debugging
`try-catch` Block
```javascript
try {
let result = x / 0; // Error if x is undefined
} catch (error) {
console.log("Error: " + error.message);
}
Debugging with `console.log()`
```javascript
let a = 5;
console.log("Value of a:", a); // Debugging output
10. DOM Manipulation and Events
Accessing DOM Elements
```javascript
let heading = document.getElementById("title");
heading.textContent = "New Heading";
Event Handling
```javascript
document.querySelector("button").addEventListener("click", function() {
alert("Button clicked!");
});
