Imperative vs declarative programming

Hello, everyone! I hope you have a couple of minutes to read this article about imperative vs declarative programming. I’m sure, you must have questioned yourself: “What are the advantages and disadvantages of imperative and declarative programming?” For you to find the answer, I propose to read my article.

In that event, I have a well-known quote: “Programming isn’t about what you know; it’s about what you can figure out”. I reckon this topic will be notable and helpful. So, let’s go!

What does imperative and declarative programming mean?

Imperative programming

So, what is imperative programming? The shortest way to answer is to explain that by using the programming language we want to say how it is used. Imperative programming is the oldest programming paradigm.

Imperative programming describes how the program operates. This means that the original code for it is a set of commands. They indicate what a computer has to do – and when – in order to ensure the expected result.

Declarative programming

It would also be interesting to tell what declarative programming is. The definition of declarative programming is widely used. It is used even more than the definition of the imperative one. Declarative programming allows you to announce what you want to be done. So, it is a more simple way.

Advantages and disadvantages of imperative programming

First of all, let’s start with imperative programming. 

Imperative programming languages are very special. Moreover, the operation here is system-oriented. Lots of programming languages founded on the imperative programming model now. Surely, it has advantages and disadvantages.

In the first place let’s take a look at advantages:

  • The languages are quite easy to learn and read.
  • The notional model is very simple for newcomers to understand.
  • Features of specific applications can be taken into consideration.

But also this kind of programming has disadvantages:

  •      The code becomes very wide.
  •      Greater risk of mistakes when editing.
  •      Updates and extensions are more difficult to provide.

From these facts, one may conclude that these imperative and declarative programming has advantages and disadvantages.

Advantages and disadvantages of declarative programming

The declarative programming is used in various facts of the case. Declarative code is described by a high level of abstraction. This allows developers to show difficult programs in a compact form. Anyway, the level of abstraction in declarative programming also offers advantages. Let’s get into them:

  • Short, effective code.
  • It can be applied by using ways yet not known at the time of programming.
  • Easy extension, the realization of which is monitored by the system.

Next, let’s talk about declarative programming disadvantages:

  • Sometimes it is difficult to understand for outside specialists.
  • Dependence on an unknown theoretical model for developers.
  • You must admit that it is difficult to take into account personal requirements during programming.

It is clear from this observation that declarative and imperative programming has advantages and disadvantages. Declarative programming and imperative programming are two different approaches that offer different ways of working on a given project or application.

Types of imperative programming

Another key thing to remember about imperative programming. I thought you might be interested to read about this programming in a categorized manner. This programming can be divided into three types. Here are the following types:

Procedural programming 

Procedural programming works with a process in terms of the machine model. This type has the ability to recycle the code.

Object-oriented programming 

Do you know that this programming is famous for using objects and classes? Objects will work together to provide practicality what your application needs. These objects are basic construction blocks of an application.

Parallel processing approach

This approach is a method of concurrently processing instructions. Parallel processing is useful when running programs that perform complex operations. And the best programming examples of these approaches are C/C++.

As a result, there are a few types of imperative programming. These types are very different and useful.

Types of declarative programming

Therefore, declarative programming also has a few types.

Logic programming

Logic programming is mostly based on formal logic. This programming shows details and rules about problems within a system of mathematical reason.

 Functional programming

Functional programming is a procedure of building computer software by forming pure responsibilities preventing shared state and mutable data.

Hopefully, that should clear up a little more about types of declarative programming. You may have been searching for what that types certainly mean.

Imperative vs declarative programming: which one to choose?

There is no exact right or incorrect type to use. Everything depends on your skills and personal choice.

If you ask me which programming you can use? In my opinion, I’d choose imperative programming. Because it is very simple for beginners to understand. 

But the choice is always yours. These imperative and declarative programmings are like chalk and cheese.


So, it’s high time to the end of this topic, which I hope was useful for you. I hope this topic “Imperative vs declarative programming” helped you to get some more information about this programming now. 

To conclude everything up, I’ll give you short information about imperative and declarative programming.

Also, I hope you also understood the pros and cons of these types of programming. There is a lot of advantages and disadvantages to both programming languages but only you can use what you want.

And the last point of topic was types of imperative and declarative programming. Here are the lists of them:

Types of imperative programming 

  • Procedure programming 
  • Object-oriented programming 
  • Parallel processing approach

Types of declarative programming

  • Logic programming 
  • Functional programming
