It is closely related to abstraction and generalization. 25 most modern languages are in varying degree both imperative and functional but to better understand functional programming, it will be best to take an example of pure functional. I can make a class an error boundary in react by implementing componentdidcatch.

So the following broadly promote functional style: A function that takes n arguments and returns a value. If the program is executed, this function is logically.
The question was difference between function and functional not definition of functional.
Is there a clean approach to making a functional component into an error. What is the difference between procedural. In functional programming we build immutable programs by using pure functions. How can i do so?
Functional interfaces should of course only be used where it is reasonable, and not everywhere. What is the real difference between acceptance tests and functional tests? I guess the difference is when we refer to functional we mean a set of possible functions; Functional programming is not about lambdas, it is all about pure functions.

What are the highlights or aims of each?
A functional language (ideally) allows you to write a mathematical function, i.e. This what pure functions are: Since there's no instance this, i cannot call this.forceupdate(). Everywhere i read they are ambiguously similar.
Only use function arguments, do not use global. (i mention about pure functions because functional programming is based on.
