When top companies like Google, Uber, etc., choose languages, they ensure considering each factor, benefits, and drawbacks that the language can have on their business. Golang has become highly popular among web developers and big players in distinct industries.

Are you convinced opting for Golang over any other programming language for your next project development?
Hire Golang developer from us and leverage the perks of this modern charismatic programming language.

Here are the 3 core reasons why are these top companies using Golang and have made it a popular choice. Let’s start with why Golang is the ideal choice for top companies.

1. Created For Multi-core Processing

Keeping cloud computing in mind, Golang was created to leverage parallelism and concurrency rendered by the latest hardware. Its take on concurrency is quite easy to work with. Additionally, when comparing python and java with Golang, running a particular function on a goroutine requires the least boilerplate code.

This channel-based and goroutine concurrency make it extremely easy to use all the available CPU cores besides handling concurrent IO without complicating development.

2. Build For Large Projects

With time, new and complicated systems were created on top of the existing foundational libraries/systems and languages. Another vital part is, people, skip the intensity of complex hidden costs. The truth here is that the code is read 10x times more than written. Team velocity is essentially loaded with complexities.

Here, Go code is highly straightforward besides being readable. This simple nature boosts teams to collaborate in brand new ways like never before.

3. Easy Learning Curve

The next to no layout and specifications of Golang makes it extremely easy to use and read. The best part is that beginners or novices entirely new to programming face zero problems reading the Golang.

However, one bonus point is, if you have knowledge or background in Java or C, Go can be highly easy to learn. Or, if you are familiar with any other programming language, learning Golang will hardly take you around a week.

However, it will be easier to grasp the language even as a beginner if you don’t. Depending on your dedication, it will take a few weeks to months.


Golang is an excellent default language. It strikes a critical balance between developer productivity and performance. Golang projects are perfect for servers, daemons, systems, APIs, websites, tools, databases, etc. Check out the power of Golang at our best Go programming language tutorials.
