NEW QUESTION # 129
Which two characteristics are true for Lightning Web Component custom events?
Choose 2 answers

  • A. Data may be passed in the payload of a custom event using a property called detail.
  • B. By default a custom event only propagates to its immediate container and to its immediate child component.
  • C. By default a custom event only propagates to it's immediate container.
  • D. Data may be passed In the payload of a custom event using a wire decorated properties.

Answer: A,C

Explanation:
The correct answer is C and D because they are the characteristics of Lightning Web Component custom events as described in the Salesforce documentation1. A custom event is an event that a component fires to communicate data to other components. By default, a custom event only propagates to its immediate container, which is the component that created it or the component that hosts the component that created it. To propagate the event beyond the immediate container, the component that fires the event must set the composed property of the event to true. A custom event can pass data to other components in the payload using a property called detail, which can be any JavaScript object. The other options are incorrect because they are not true for Lightning Web Component custom events. Option A is incorrect because a wire decorated property is a property that is automatically updated with data from a Salesforce org or an Apex method. It is not related to custom events. Option B is incorrect because a custom event does not propagate to its immediate child component by default, unless the child component is the one that fires the event or the event is composed.
