Refer to the Aura component below:

A developer receives complaints that the component loads slowly.

Which change can the developer implement to make the component perform faster?

Show Suggested Answer Hide Answer
Suggested Answer: D

The correct way to fix this is to add Test.startTest() before and add Test.stopTest() after Line 18 of the code. This will reset the governor limits for the code that executes between these two methods, and allow the test to run without hitting the SOQL query limit.The Test.startTest() and Test.stopTest() methods are used to test code that makes a lot of queries or calls asynchronous methods12. By using these methods, the developer can isolate the code that needs more resources and verify that it does not exceed the governor limits.

Wait, does changing to 'Map' really make a difference? Sounds odd.

I'm a bit confused by this question. I'm not sure which of these options would actually make the component perform faster. I think I'll need to do some more research on Aura component optimization before I can confidently answer this.

I'm leaning towards option D, changing the default for showContactInfo to 'False'. That way, the component wouldn't have to load all the contact info data unless the user actually wants to see it, which could make the initial load faster.

Okay, let's see. Based on the information provided, I think changing the type of contactInfo to 'Map' might be the best option. That could help reduce the amount of data being loaded initially, which could improve the component's performance.

I'm feeling pretty confident about this one. The key is understanding the differences between the container types and how they interact with the queue constructor. I'll work through it step-by-step.

I've got a better idea - let's just turn the whole component off. That'll make it load lightning fast, am I right?
