JavaScript Number Pattern 15

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>=1; j--)
  document.write(j % 2);
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

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

🧠 How the Program Works

Let's break down the logic behind the code:

The var i, j; statement declares two variables, i and j, which will be used as loop counters.
The outer loop (for(i=1; i<=5; i++)) runs five times, with i starting from 1 and increasing by 1 in each iteration, until i becomes 5.
Inside the outer loop, there's an inner loop (for(j=i; j>=1; j--)) that runs from the current value of i down to 1. In each iteration of the inner loop, the value of j decreases by 1.
Inside the inner loop, the statement document.write(j % 2); is executed. Here, j % 2 calculates the remainder of dividing j by 2, which will result in either 0 or 1. This effectively generates an alternating pattern of 0s and 1s.
The document.write(j % 2); statement writes the calculated value (0 or 1) to the document.
After the inner loop completes, the statement document.write("<br>"); is used to add a line break, creating a new line in the output for the next iteration of the outer loop.
The outer loop continues to iterate until i reaches 5. As a result, the entire pattern is repeated five times, each time with a new line of alternating 0s and 1s.

💯 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.
