JavaScript Number Pattern 2

Here`s a program that prints the above number pattern using JavaScript Programming:

example.html

Copied

<!DOCTYPE html>
<html>
<body>

<script>
var i, j;
for(i=1; i<=5; i++)
{
 for(j=i; j<=5; j++)
  document.write(j);
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

When you run the above program, it will print the following output:

Output

🧠 How the Program Works

Let's break down the logic behind the code:

<!DOCTYPE html>: This declares the document type as HTML5, indicating that the content of the document follows the HTML5 specification.
<html>: The opening tag for the HTML document.
<body>: The opening tag for the body of the HTML document, where the visible content is placed.
<script>: This tag indicates the start of a JavaScript code block.
var i, j;: This declares two variables, i and j, which will be used as loop counters.
for(i=1; i<=5; i++): This is a for loop that initializes the variable i to 1, runs as long as i is less than or equal to 5, and increments i by 1 after each iteration.
The opening curly brace { indicates the beginning of the loop's block of code.
for(j=i; j<=5; j++): This is an inner for loop that initializes the variable j to the current value of i, runs as long as j is less than or equal to 5, and increments j by 1 after each iteration.
The opening curly brace { indicates the beginning of the inner loop's block of code.
document.write(j);: This JavaScript statement writes the value of variable j to the web page.
document.write("<br>");: This statement writes a line break (<br>) to the web page, causing the next number to be displayed on a new line.
The closing curly brace } marks the end of the inner loop's block of code.
The closing curly brace } marks the end of the outer loop's block of code.
</script>: This tag indicates the end of the JavaScript code block.
</body>: The closing tag for the body of the HTML document.
</html>: The closing tag for the HTML document.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
