Choose 3 answers

A. Loading scripts in parallel
B. Specifying loading order
C. Loading externally hosted scripts
D. One-time loading for duplicate scripts
E. Loading files from Documents

Answer: B,C,D

Explanation:
Option A: Specifying loading order
True.
The <ltng:require> tag allows you to specify the order in which scripts are loaded by the sequence in the scripts attribute.
Scripts loaded using <ltng:require> are loaded only once, even if multiple components request the same script, preventing redundant loads.
You can load scripts from external URLs, such as Content Delivery Networks (CDNs), using the scripts attribute.
<ltng:require> cannot load files from the Documents object. It loads resources from static resources or external URLs.
Scripts are loaded sequentially, not in parallel, to ensure dependencies are properly resolved.
Reference:
Include External JavaScript and CSS Libraries
Option B: One-time loading for duplicate scripts
True.
Loading JavaScript Libraries
Option D: Loading externally hosted scripts
True.
Using External Libraries
Option C: Loading files from Documents
False.
Static Resources
Option E: Loading scripts in parallel
False.
Scripts Loading Order
Conclusion:
The three capabilities are A, B, and D.
