It depends on what you want to achieve, just like with anything else. Gaming continues to be the most popular use of VR technology. According to several polls, C# and C/C++ are the two most popular programming languages for VR apps if you want to work in the game sector. The great thing is that the two most popular game engines used (Unity and Unreal Engine, utilising C# and C/C++, respectively) are supported by the majority of VR devices, even if both systems have a somewhat high learning curve. Additionally, these devices offer quite advanced software development kits (SDKs). You just need to master one platform, therefore.

C#

For a variety of reasons, mastering the Unity game engine is a wise choice if you're just getting started. It is, by far and away, the more popular game engine. The most common programming language for building Unity apps with this engine is C#. The majority of VR applications are written in Unity, and it functions on both PC and Mac. It's practically a no-brainer to use the most widespread language with the most popular engine. Should you require assistance with development, it also boasts a wide network of employed designers.

JAVA

Java, this flexible programming language (created centuries ago by Sun) works well for VR applications that aren’t necessarily gaming. This object-oriented language is helpful for cross-platform programmes, much like C# (PC and Mac). In fact, Java is generally the first subject that engineers and computer science students meet in college since it provides the requisite applications and capabilities needed for efficient VR creation. Using VR technology, users may train in simulated surroundings and evaluate items in real time. At the core of the digital transition will be VR technology. The industry will witness the fusion of augmented reality (AR) and virtual reality (VR) to create a mixed reality that will be used for gaming and educational applications.

C++

But because it's a little trickier to understand C#, the Unreal Engine is a little more potent and is sort of considered the "adult" version. C++ is the preferred language for this engine. C# is a good choice if you're doing anything on a small scale, but if you require more, Unreal and C++ are what you need.

Like practically anything else, each platform has advantages and disadvantages. Both engines have free options for use; Unreal is free up to a limit, after which royalty payments apply and Unity has a free version and several subscription (pay) services. Once more, it pays to properly investigate them and select the solution that suits best for you.

JAVASCRIPT

The language of the internet is JavaScript. It is a widely used and simple programming language that shares lexical syntax with the more sophisticated C programming language. Since it’s the language comprehended by most web pages, JavaScript works well for the WebVR forum involved in formation of web based Virtual Reality apps. It works with programmers to quickly produce VR applications on the web (and for download). It's difficult to go wrong by starting out with an accessible system that is also the internet's primary language. In essence, if you're just starting out in the world of VR programming, this might be your best option. If not, you should make this language the cornerstone of your skill set.

PYTHON

Python, which is among the simplest programming languages to learn, is an excellent language to learn for someone who is just starting out in the VR development industry. The language itself is fairly simple to comprehend, and it enables users to develop their ideas with fewer lines of code. Thus, in addition to being simpler, it is also quicker. Due to several intriguing Python-related packages, developers can quickly create VR projects (it has a unique way of downloading and resolving issues).

Furthermore, a developer may advance to one of the four primary VR languages without too many obstacles or a high learning curve provided they have a strong foundation in Python and Unity.
