A new idea before you use ittest case

A test case is one example with a setup, an action, and an expected result.

A familiar way to picture it

A cashier checks one sample basket before opening the counter.

Known setup
Run one action
Observed result

You will write one focused example for a function.

Current Task

Create one test case with an input and expected result.

Take your time with this step

Take this one change at a time. Look for the file and line named in the instruction, make the requested edit, then press Run. If a check does not pass yet, use its message to decide what to inspect before changing anything else.

What the checker will look for

These checks are clues, not a score. After you press Run, read the first unfinished check slowly, compare it with your code, and make one thoughtful change before trying again.

The test keeps input and expected values
The test case describes one example

Run your code first. If a check needs work, CodeDaddy will guide you from the check to the file, then to an authored hint.

function double(value) { return value * 2; }
