Sample JavaScript Examples for Understanding:

1. Declaring Variables and Basic Output:

   javascript
   var greeting = "Hello, JavaScript!";
   console.log(greeting);
   

2. Conditional Statements:

   javascript
   var age = 25;
   if (age >= 18) {
       console.log("You are an adult.");
   } else {
       console.log("You are a minor.");
   }
   

3. Functions:

   javascript
   function addNumbers(a, b) {
       return a + b;
   }
   var result = addNumbers(5, 3);
   console.log("Sum: " + result);
   

4. Working with Arrays:

   javascript
   var fruits = ["apple", "banana", "orange"];
   fruits.push("grape");
   for (var i = 0; i < fruits.length; i++) {
       console.log(fruits[i]);
   }
   

5. DOM Manipulation:

   javascript
   var heading = document.getElementById("main-heading");
   heading.textContent = "New Heading";
   

6. Event Handling:

   javascript
   var button = document.getElementById("my-button");
   button.addEventListener("click", function() {
       alert("Button Clicked!");
   });
   

7. These sample JavaScript examples provide a glimpse into the fundamental concepts covered in the course. Learners can practice and explore these concepts in-depth as they progress through the modules.
