Prompt 1

I've created example.js, a representative JavaScript example file that demonstrates basic language features including:

• Class definition with constructor and methods
• JSDoc comments for documentation
• Functions including recursive (factorial) and iterative (fibonacci)
• Async/await and Promises
• Array methods (map, filter, reduce)
• Object manipulation with Object.entries
• Destructuring assignment
• Spread operator
• Template literals for string interpolation
• Arrow functions
• ES6+ module pattern

The file runs successfully and follows a similar structure to the existing Python, Go, and Ruby example files in the repository.
