Is functional programming better than imperative?

The functional programming paradigm was explicitly created to support a pure functional approach to problem solving. Functional programming is a form of declarative programming….Functional programming vs. imperative programming.

Characteristic	Imperative approach	Functional approach
State changes	Important.	Non-existent.
Order of execution	Important.	Low importance.

What are the drawbacks of imperative style of programming?

Advantages and disadvantages of imperative programming languages

Advantages	Disadvantages
Easy to read	Code quickly becomes very extensive and thus confusing
Relatively easy to learn	Higher risk of errors when editing

What is functional programming and why is it important?

Functional programming is one of these techniques. It simply suggests that problems should be solved using functions and states should be avoided. Every programming paradigm uses simple building blocks to construct a program. In this case, functions happen to be fundamental items.

Should we avoid mutable state in functional programming?

Any side effect or mutable state should be avoided at any complexity cost. But some other languages (e.g. F#) combine many programming methods. They take good and strong parts of functional programming, and they encompass these methods with other paradigm’s methods.

What is the difference between currying and partial function application?

Partial function application is related to currying but they are distinct concepts. In currying, you give each argument one by one. If you make an argument constant, the whole function depends on the remaining arguments: The function is partially applied. For example, think of a function add x y.
