03 / TRY IT

Prepare a focused example

Choose one question about Functional Programming that you want to answer.
Write down a small example, its inputs or starting point, and the result you expect.
Explain your reasoning and note what you would like reviewed in a live or 1:1 session.

Keep your work

A short example, reasoning and an open question

Check your understanding

Explain the concept in your own words and identify where it fits in the subject.
Show one small example, the expected result and the reasoning behind it.
Record one limitation or edge case and a question to discuss with a mentor.
