✦ Synopsis

The schism between the functional and object-oriented programmers is really a false binary. Yes, the first group argues that FP is superior for a multicore world, while the second insists that OOP is better at matching technical solutions to business problems. However, as this O’Reilly report explains, this is not an either-or proposition.

Technologist Richard Warburton, author of Java 8 Lambas, discusses similarities between these programming paradigms and points out that both FP and OOP are actually moving closer toward one another. One prominent example is the use of lambda expressions in Java and other OOP languages such as C#, C++, and Swift.
