In modern software development, performance and user experience play a major role in application design. Users expect applications to respond instantly, and even a small delay can impact engagement. One technique used to improve responsiveness is Optimistic Preloading.

What is Optimistic Preloading?

Optimistic preloading is a technique where an application loads data or resources before the user explicitly requests them. The system predicts what the user is likely to do next and prepares the required content in advance.

The term optimistic comes from the assumption that the prediction will most likely be correct.
