Asynchronously load the Facebook SDK only when needed.

JavaScript July 2, 2019


This function runs automatically, so it is not called manually. Is this incorrect?

Additional Notes

This function looks for elements with a class that begins with fb- or a class of require-fbsdk anywhere to force it to load.
