Salesforce JavaScript Developer I Exam Practice Questions with Answers

Question 1: What is the purpose of the @wire decorator in Lightning Web Components?

Answer: The @wire decorator is used to connect a Lightning Web Component to a Salesforce data source or Apex method. It enables reactive data fetching, automatically updating the UI when the data changes.

Question 2: Which JavaScript method is used to merge multiple objects into one?

Answer: The Object.assign() method is used to copy properties from one or more source objects to a target object.

Question 3: Explain the difference between map() and forEach() in JavaScript?

Answer: The map() method creates a new array with the results of calling a provided function on every element in the array. In contrast, forEach() executes a provided function on each array element but does not return a new array.

Question 4: What is a promise in JavaScript, and why is it important in Salesforce integrations?

Answer: A promise represents a value that may be available now, or in the future, or never. In Salesforce, promises are critical for handling asynchronous operations like API calls or server responses without blocking the UI thread.

Question 5: How does the Lightning Web Components framework improve performance compared to Aura components?

Answer: LWC leverages native web standards, which reduces the framework's complexity and improves runtime performance. Its lightweight nature results in faster component rendering and enhanced scalability.
