App structure

Question

What programming language is apps made of? Is it the common languages like html,css,js or is it something else like kotlin?

Answer 1

It depends on a variety of things.

Web technologies (HTML/CSS/JavaScript are used for web apps, react, react native.

Java/Kotlin are used primarily for Android apps, but can also be used for native apps on Windows, Linux, or Mac.

C, C++, and C# are also used for native apps. A great place to start might be C# with .NET.

C++ and C# are frequently used for game development, depending on which game libraries you are using.

Swift, Go, Java, and Kotlin are all common choices for mobile app development.

Many business apps are built using web technologies as it is easier to maintain since the code exists only in one place. Back-ends for those web apps might include a number of languages but the front-end would be HTML/CSS/JavaScript.

So it depends on what you want to build. A great start is to learn HTML, CSS, JavaScript and maybe some SQL. That enables you to build web apps. Then use a framework like REACT or Angular.

Fundamentals are key as you may need to learn different languages for different applications. If there is a specific app you want to develop, it's best to figure out what languages best suit that app's requirements.

Answer 2

Many mobile and web apps are made using Java and web technologies (html, css, js etc).

Many desktop gui are made using Java, python

Many games are made using Java, web technologies, c++, c#

I want you to observe a trend in all these sets, Java is an intersect of all the three sets
