Shape the data first
Why this matters
You are inside the section “Working with data” of the JavaScript Essentials track. Everything in this section builds towards the section project, and this task is one of the pieces that project leans on.
Reading code and understanding how it behaves is the skill that separates people who copy answers from people who can fix a broken program at 11pm. That is why concept steps exist between the coding tasks.
The key idea
Every task in this track is small on purpose. Small, finished and understood beats large, impressive and half-working.
Read the whole task before you touch the keyboard. Two minutes of thinking saves twenty minutes of guessing.
Before you continue
Say the idea out loud in one sentence, without using the word “it”. If you cannot, read the section above once more — the next task assumes this one is solid, and the checkpoint quiz after every ten tasks will ask about it.

What should you design before rendering?
This is a concept step: there is nothing to type. Read the left column, then click Mark as read and continue in the right column to unlock the next task.
Every concept task contributes to the quizzes that unlock after every 10 finished tasks.
