Functional programming is at last mainstream. The most popular JavaScript frameworks React and Vue has adopted functional rather than OOP approaches. Before long we will see how functional programming fares when applied by average programmer under real-world constraints and the consequences for long term maintainability. Like when OOP hit the mainstream, I predict we will see some disappointment set in. Due to the laws of the hype-cycle, this will lead to embarrassment and backlash, but in the end expectations will stabilize, and functional will be considered a tool in the toolbox rather than a panacea.
