This example demonstrates a simple interactive event-handling pattern for HTML links. Two links, each bound to a separate instance of a JavaScript `Obj` constructor, respond to clicks by logging a greeting to the console. The code relies on native DOM APIs such as `document.getElementById` and the `onclick` property, while closures capture each instance’s current `word` property. The first link logs “Hola testa” after the property is reassigned, while the second logs “Hello testa,” illustrating how per-instance state persists. No external libraries or data sources are used; the behavior is purely client-side.
