Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a getter function that evaluates the wired property and returns the formatted result.
Wired data can be handled via wired adapter property results using a getter, a wired function that transforms the value into a tracked local property, or custom wire adapters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Directly mutate the object properties returned by the wire adapter inside the template.
Why it's wrong here
Incorrect. Wired data is immutable; direct mutation causes runtime errors.
- ✓
Use a getter function that evaluates the wired property and returns the formatted result.
Why this is correct
Correct. Getters can derive formatted values reactively from wired properties.
- ✓
;Transform data within an Apex method before returning it to the wire service.
Why this is correct
Correct. Preparing and formatting data directly in Apex before wire delivery is a valid and efficient pattern.
- ✗
Use the renderedCallback() hook to modify the raw wired data object directly.
Why it's wrong here
Incorrect. Mutating state in renderedCallback() can lead to infinite render loops.
- ✓
Use a wire adapter function (property-and-function syntax) to process data into a local reactive property.
Why this is correct
Correct. Using a wire function allows processing data before assigning it to local component properties.
