Nowadays, knowledge of the Go language is one of the highest-paid skills. Go is one of the most rapidly evolving programming languages. When there are dozens of programming languages to learn and use, then why Go? What is it? Where does it come from? What are the advantages and disadvantages of using Go? Where should we use it? In this article, we will see the answer to these questions.
What is Go?
Go, aka Golang, is an open-source programming language, developed by Google. Googlers wanted to have a language that manages multi-threading, is compiled in a shorter time and is easy to understand. They also wanted it to have a similar syntax to C or Java so that it would be easy to learn and switch to. Golang allows the engineers of a company to have better productivity and use hardware resources more efficiently. Golang was designed in 2007 but it was launched in 2009. Nowadays, big companies like Uber, Netflix, Twitch, Dropbox, and BBC use Golang. Many other organizations and open-source projects use Golang as well. Go is a statically typed and procedural language. It has a clean syntax which is similar to C. In general, Golang strikes a balance between performance, control and the developer’s experience.
Golang is designed by Google. As you know, Google products are so efficient and user-friendly. This minimalist language is one of the top programming languages developers want to learn. IT companies prefer Golang because of its simple and modern structure. Go is popular among data scientists due to its high performance. Let us see some other advantages of this programming language which makes it the most in-demand language in the world.
Go is Fast
Golang is fast because it’s translated into machine code, while other languages are compiled into bytecode. It’s a compiled language. As a result, the codes written in Go are compiled directly to a format that the processor can understand. Moreover, this programming language is designed to allow the compiler to quickly analyze dependencies and avoid loading files repeatedly. This leads to fast compilation.
Go is Concurrent
Threads are commonly used to make a concurrent program. But Golang introduced goroutines as an alternative to threads. Threads are not efficient when using hardware resources. Goroutines help reduce the use of hardware resources. Many Go applications can run tens of thousands of goroutines concurrently without issue. Unlike threads, which communicate by sharing memory, goroutines communicate via channels. Altogether, this programming language works well with multicore and networked systems, and large codebases.
Go is Easy to Learn
Go is grouped into beginner to intermediate level languages. Golang has a simple syntax compared to other languages. It is said that if you are already a developer, you can learn Golang in a few hours. The syntax and procedural approach in this programming language are similar to C and Java. Go’s syntax is also clean and easy to read. Even non-Go programmers can read Go code and understand it.
Go Has Accessible Development Tools
Since Go is an open-source programming language, there are a variety of development tools available. Many developers still prefer text editors, but Golang IDEs are becoming more popular too. Frameworks let developers create applications as easily and quickly as possible. You can choose among different frameworks, plug-ins, editors, and IDEs to code in this language.
- Backed by Google
- Statically typed
- Garbage collection
- Smart documentation
- Built-in testing tools
No programming language is perfect. Go has its own downsides, too. Before switching to Golang, you’d better consider a few things.
Go is a Young Language
Although Go has been around for more than 10 years, it is considered a young language. Older languages like Java, have the support of a vast collection of built-in functions and existing libraries. This programming language lacks SDK and third-party interfaces. Go developers may have to write the libraries themselves. When in doubt, there are not many books or online courses to help. Also, programmers may struggle and require a significant amount of knowledge, particularly when interacting with other platforms.
Go Lacks Generics
Generic functions are a set of distinct functions with the same name, but with undefined types of inputs at compile time. As Golang does not support generic functions, programmers must write multiple functions to manage different parameters. Due to a shortage of code reusability, this lack of support vastly reduces development efficiency. Generic type is probably the most demanded feature for Go users.
Go Has Poor Community Support
Other popular programming languages have a large developer community around the world. Golang, as a relatively new language, has a small community in comparison to other popular languages. However, as the use of Golang grows, this limitation will be overcome.
- Dead simple error handling
- Hard dependency management
- A high-level language, with low-level features
Where Should We Use Golang?
Go is one of the best programming languages, but we cannot use it for every project. Golang might be a good option for large projects. But small start-ups might want to spend their time in other areas rather than coding. Let’s mention some apps and services that are reaping the most benefits from this programming language.
- Media platforms
- On-demand services
- Cloud services
- Broadcast providers
Golang has the potential to become the most popular programming language in the world. It has some really cool tools and features. However, there are numerous things that can be improved. Golang was created to fill in the holes left by C++ and Java in Google’s servers and distributed systems. It’s no surprise that this language has gained such a big following among developers all over the world. Go has a bright future, but in some areas, it cannot compete with other languages.
