When should I use functional programming?

When should I use functional programming?

If a project requires lots of concurrency/parallelism, its own language, or lots of math, you should think functional programming. As IT professionals, we have to balance proficiently executing on current projects with proven technologies and learning to implement new ways of doing things.

Is JavaScript good for functional programming?

Functional programming is a well-researched and robust paradigm of writing computer programs. With the introduction of ES6, JavaScript allows for a much better functional programming experience than ever before.

Is JavaScript functional or imperative?
