What is App Development & What are the Best Languages for It?

Whether you’re a techie or not, you’ve probably heard of apps. But, what is app development? In this blog, we answer that question and look at the best languages for it.

Even those who do not use smartphones often use various apps on a daily basis, such as the alarm app. As a result, applications have become increasingly popular over the years. Previously, apps were made for complex ideas such as gaming, eCommerce, social networking, and so on, but now you can find apps for tracking water intake, exercise, meditation, etc. 

Which explains why the need for app development is increasing at a rapid rate. App development is not challenging, and developers can swiftly advance through the levels. The most common challenge, however, is determining the best learning strategy. 

So, here’s a comprehensive guide on learning app development, including how to get started, what to study, and where to learn it.

What is App Development? 

App or application development is the intricate process of designing, implementing and developing mobile applications. The applications are either developed by independent professional freelancers or by a team of skilled developers belonging to a giant firm.

Initially, app development intended to replace desktop computers with smartphones. Developers created such applications like word processors and other applications. However, when smartphones became more widespread, every organisation and individual began to build applications in various genres, including games, social networking, retail, and other miscellaneous categories.

There are countless aspects to consider when it comes to application development, such as the size of the app, the design, the concept, and many more. To obtain optimum results, a proficient developer should be knowledgeable in all of these areas.

Is it, however, simple to create an application?

The answer is up to you. It is really simple to develop an app if you understand and practise adequately.

What are the Best Languages for App Development?

If you plan to become a talented professional app developer, your first step would be to learn the basics of app development, that is, proficiency in programming languages.

Before we jump into what programming languages to ace in app development, there are two concepts you should be aware of: Front end and back end.

Front end:

The front end, or the app’s user interactive display, relates to the design, theme, fonts, presentation, graphics, and other elements. If you want to master frontend development, you should master relevant languages such as HTML, CSS, and JavaScript.

Back end:

The back end, or the component of the programme that is not visible to the user, refers to the app’s speed, size, efficiency, and security. 

In the same way that there are particular languages for programming frontends for apps, unique languages for programming servers and databases for applications. Some of these languages include Python, Ruby, and others.

To become an app developer, you can either learn front end or back end or even both. Whatever your choice is, you must understand and master a handful of languages to create at least a mini-project.

So here are some of the programming languages that are well known for app development.

  1. Java
  2. Kotlin
  3. Dart
  4. Swift
  5. Python
  6. C++
  7. JavaScript

Java

Java is an approved language for developing Android apps. Therefore, to commence your app developer journey, studying Java will most likely not only help you master app development rapidly but will also assist you in quickly understanding other relevant languages.

How to Get Started in App Development?

We now know “What?” to learn in order to become a professional app developer. Now let’s look at “How?” to get started on your journey to being a successful one:

Choose a Platform

The first thing, even before choosing a programming language, one should decide on which platform they are writing the program for. As we all know, there are two major platforms for mobile applications: iOS and Android. So, to begin, choose one of the two options.

You can choose one or both, but you must be familiar with two concepts: native development and cross-platform programming.

Native Development: Developers choose one platform and produce programmes exclusively for that platform, which is known as native development. If you’re a native Android developer, you create native Android apps that only run on Android; similarly, if you’re an iOs developer, you build native iOS apps that only work on iOS.

Cross-platform Development: Cross-platform development is the term used to describe applications that are created once and can operate on any platform, including Android and iOS.

After choosing the above options, one should learn the related programming languages. 

Learn Core Concepts

Having a solid grasp of fundamentals is necessary to become a versatile app developer. 

Programming, may it be, any field has some common core concepts. Without mastering them, building complex applications will become tedious.

The following are some fundamental notions in every programming language:

  • Variables
  • Data structures
  • Syntax
  • Control structures
  • Tools

Choose a Good Programming Course

One needs a mentor to grasp and understand the intricacies of a programming language or a related profession.

Before choosing the right course, make sure that course is for you. For example, if you are a beginner, choose courses that are created for beginners that can give you a generous tech stack. On the other hand, if you already have adequate programming knowledge, you can either choose the beginner ones or go for intermediate ones.

Join the Community

Each and every programming language has a dedicated community that is active with a vast number of skilled developers. Joining such communities will help you keep up to date about the latest features and tactics of the particular language.

Some of the popular platforms for programming communities are:

For instance, if you are learning Python, join the Python community on any of the above platforms. The same goes for other programming languages. 

Also, if you have any queries regarding any errors of concepts, you can find answers in these communities since most doubts you face are not new.

Build Mini Applications

While learning app developments, try putting your knowledge into work during the learning period instead of waiting for the course to end.

Try building mini-applications at first. It can be as simple as a Hello World app that displays ‘hello world’. Then try upgrading to the calculator, memo, weather forecast and many more.

Since programming is a skill that grows only through practice, it is essential to practice while learning.

While developing mini-projects, it is also customary to face errors. Instead of relying on communities, try resolving the mistakes on your own. Doing so will enhance your problem-solving ability, which is a great skill that every recruiter looks for in a developer.
