JavaScript code is usually placed inside <script> tags in an HTML file. Example:
<script>
console.log("Welcome to AIT!");
</script>
Feedback: This is the basic JavaScript structure that is essential for every website!
You can print messages using console.log(). Example:
console.log("Hello, welcome to aitaurangabad.com!");
Feedback: Printing messages in the console is very helpful for debugging.
Variables store values like numbers or strings. Example:
let age = 21; // Storing age
let name = "Zaid"; // Storing name
Feedback: By using variables, we can manage data
JavaScript has multiple data types such as numbers, strings, and booleans. Example:
let isStudent = true; // Boolean value
let score = 95; // Number
let greeting = "Hello!"; // String
Feedback: By using different data types, we represent specific types of values.
Operators help you perform operations like addition or comparison. Example:
let sum = 10 + 5; // Adds 10 and 5
let isEqual = (10 == 10); // Checks if 10 equals 10 (true)
Feedback: By using operators, we can perform calculations and make comparisons.
Expressions combine values and operators to get a result. Example:
let total = (5 + 3) * 2; // Adds 5 and 3, then multiplies by 2 (result = 16)
Feedback: By performing operations in expressions, we generate dynamic values.
Functions are reusable blocks of code. Example:
function greet(name) {
return "Hello, " + name + "!";
}
console.log(greet("Daniya")); // Calls the function
Feedback: By using functions, we organize and make our code reusable.
Comments are used to explain code. Example:
// This is a single-line comment
/* This is a multi-line comment */
Feedback: Comments make the code easier to understand and help other developers.
