Mastering JavaScript Functional Programming

Pointfree style

When you join functions together, either in pipeline fashion as here, or with composition as we'll be seeing later in this chapter, you don't need any intermediate variables to hold the results that will become arguments to the next function in line: they are implicit. Similarly, you can write functions without mentioning their parameters, and this is called pointfree style.

Pointfree style is also called tacit programming -- and pointless programming by detractors! The term point itself means a function parameter and pointfree refers to not naming those parameters.
