Is Go The Best Programming Language For Finance? Best Practices And Softensy Expertise

By Maryna Cherednychenko

If you are going to extend your business to the digital community, you need to choose the right tech stack to develop a web or mobile solution. In the ever-changing world, technologies follow quickly one after another. A few years ago, Java occupied a leading position both in the back and front-end development. Now, new players have appeared on the horizon. One of them is Golang or Go. It is Google’s creature that aims to unite the best features of other languages. At Softensy, we often use it for high-load systems in fintech projects. If you want to know the pros and cons of Go and see what solutions it works best for, continue reading this post.

What Is Golang?

Golang Advantages

Easy to learn. For experienced developers, especially those who know C or Java, to learn Go makes no problem. While it has a slightly different syntax, the procedural approach is the same.

Scalability. With Goroutines, you can run many tasks simultaneously without being afraid that the system crushes. Each Goroutine takes up not more than 2kB, so your software will be really lightweight.

Multiple tools. Go is an open-source language with a wide range of tools for developers. You can find them in the Github repository with the step-by-step description.

Golang Disadvantages

No GUI library. If you need to implement a one-page app, the basic UI elements of the Google Go language may be enough. However, the developers will have to look for custom ways to connect the library for complex apps.

Lack of generic functions. Generic functions have the same title but undefined input data type during compilation. The absence of such functions means the developers have to create many function elements to work with various parameters.

Pros and cons of Golang

Comparison With Other Languages

Go vs. Java

Java is portable and versatile. It is intended to write once and run anywhere. Being a project-oriented language, Java is more suitable for large projects. Meanwhile, Go that has no class inheritance goes better for microservice architectures.

Go vs. Python

If we speak about the purpose, Python is mostly associated with web development and Linux-based apps, while Go is considered a system language. System languages ​​serve to create the operating systems themselves, rather than programs running on these systems.

Go vs. C++

Both C++ and Golang performance speed is nearly the same, even though Go has a garbage collector, which, in theory, slows the execution time. In practice, this difference is almost invisible unless you are going to perform massive calculations.

As for the scope of use, С++ works for many app types, while Golang projects are mostly extended to web backends.
