JavaScript help needed. Merge 2 JSON fetch responses into one dataset

I have two fetch functions that return arrays of the same structure. Both datasets contain: Name, ID, Author and Date only

I need Dataset A joining to Dataset B as a left join. They should join on the "NAME" field. 2 rows from Dataset B match the rows from Dataset A.

Here is my online sample script that needs to be edited: https://jsfiddle.net/bentham7246/p0tuar3y/45/

I've attached a mockup of the desired data table.

I would like this in plain javascript please
