| - | Map takes a function and a list vals and applies that function to each item in the list. Note that when using higher order functions in Elixir, you use ''&Module.functionName/arity'' to pass it, and ''functionName.(…)'' to call it. Thus,to test it, the call should look like this ''map(&Module.functionName/arity, list)''. | + | Map takes a function and a list vals and applies that function to each item in the list.
