How should an AI model's internal functions and user interface behave?

An AI model's internal functions must be correctly identified as getters or constants. Data should refresh as expected. User interface elements must respond predictably to user actions.

The rule

An AI model's internal functions must be correctly identified as getters or constants.

Data should refresh as expected. User interface elements must respond predictably to user actions.

An AI model's word bank function, `_CL_WORDS()`, is a getter. It is not a constant value. This means its value can change. External JavaScript loads after the main function runs. The word bank cache resets every time `_openScreen2()` runs. This ensures the AI model always uses the most current list of 10,000 words.

A developer creates an AI model that helps students learn new languages. The developer uses `_CL_WORDS()` to get a list of vocabulary. If the developer treats `_CL_WORDS()` as a constant, the vocabulary list will not update. New words added to the list will not appear for the student. If the developer treats `_CL_WORDS()` as a getter, the student always sees the latest vocabulary.

Questions people ask

More from the same record, pulled by shared topic — not written new for this page.

How can a developer scale an AI application from a small dataset to a very large one?

A developer can scale an AI application by automating data generation. This means using an AI model to create new data instead of doing it by hand.

When should an animation start on a webpage?

An animation should not start when a page loads. This defeats the purpose of letting a user choose to see it.

How can a developer handle overlapping parts in an interactive SVG chart without flicker?

Realistic diagrams often have parts that overlap. For example, a bicycle bell sits on a handlebar.

How should a developer build the user interface for new chapters?

The user interface for Chapter 1 is the master design. All other chapters must use this design.
