JScript Examples

```
Hello World (in a browser)

alert("Hello, world!");
```
This code will display a pop-up message box with the text "Hello, world!".
```
Variables and Output

var name = "Alice";
var age = 30;
document.write("Name: " + name + "<br>"); // Output to the web page
document.write("Age: " + age + "<br>");
```
This example declares two variables, `name` (a string) and `age` (a number), and then writes their values to the HTML document using `document.write()`. The `<br>` tag adds a line break. This is how you might output data to a web page using J(ava)Script.
```
Simple Function

function add(x, y) {
  return x + y;
}

var result = add(5, 3);
alert("The sum is: " + result);
```
This defines a function called `add` that takes two arguments (`x` and `y`) and returns their sum. It then calls the function with the numbers 5 and 3, stores the result in the `result` variable, and displays it in an alert box.
```
Conditional Statement (if/else):

var score = 75;

if (score >= 60) {
  alert("Passed!");
} else {
  alert("Failed.");
}
```
This code checks the value of the `score` variable. If the score is 60 or greater, it displays "Passed!"; otherwise, it displays "Failed.".
```
Loop (for loop):

for (var i = 1; i <= 5; i++) {
  document.write("Iteration: " + i + "
");
}
```
This `for` loop iterates five times. In each iteration, it outputs the current iteration number to the web page.

Arrays:

var colors = ["red", "green", "blue"];
alert(colors[0]); // Output: red
alert(colors[1]); // Output: green

This example shows how to declare and access an array in JScript.
