I have started my preparation for Platform Dev 2 (platform Dev 1 already done).While going through the certification guide for this certification, I am trying to understand if Lightning components development is in scope of this exam or not.IF it is, what is the extent to which a developer is expected to know about lightning component development?
While going through the certification guide, in Syllabus under "User interface" topic, it is mentioned:
Given a set of requirements, describe the process for designing Lightning components.
It is also mentioned in the same guide that developer:
Can build custom user interfaces to display and interact with Salesforce data using the Lightning component framework, advanced Visualforce, and moderate JavaScript.
