## Example of Jonathan Blow Programming

Here’s a simple example of code written in the Jonathan Blow Programming Language (Jai) showcasing its syntax and features:

In this example:

• We define a struct Point2D to represent a 2D point with x and y coordinates.
• We define a function distance that takes two Point2D objects as input and calculates the Euclidean distance between them.
• In the main function, we create two points p1 and p2.
• We then calculate the distance between p1 and p2 using the distance function and print the result.
