I've always been amazed by the amount of utility in the lodash library. On each project I've worked on, each developer seems to know one or two neat functions that I didn't realize were there. And I would some them one or two functions that they hadn't used.
So I thought it would be valuable to go through the library and use each of the functions there myself.
This is a suite of tests that helped me explore the lodash library in a more comprehensive way.
