Share some experiences in converting Erlang to Go language

Erlang is difficult to get started, and its form is completely different from that of object-oriented languages. However, Go language is a language that focuses on simplicity, easy to learn and use, so many developers will switch Erlang to Go language. The following is the conversion of Erlang to Go language. some experience.

1. Learn common Erlang mechanisms

Before learning Erlang, you need to understand its most basic features, such as concurrency, processes, message passing, and error handling mechanisms. These features are very helpful in converting Erlang to Go language, because Go is also a language that focuses on concurrency and error handling.

2. Study Erlang module

Erlang module is a collection of related functions, while in Go language it is a package. Being familiar with the way Erlang modules work can help you quickly adapt to the way Go and packages work.

3. Get familiar with processes in Erlang and Go

Both Erlang and Go support processes, but there are differences between them that need to be noted. In Erlang, processes are lightweight and tens of thousands of them can be created, whereas Go runs each thread independently.

4. Mastering Message Passing in Erlang and Go

Erlang and Go are both based on message passing. Mastering message passing in Erlang will help you quickly understand channels and communication mechanisms in Go.

5. Learn the basic concepts of Go language

Be familiar with the basic concepts of Go language such as variables, functions, structures, interfaces, etc. These concepts have no equivalent in Erlang concept.

6. Familiar with the Go network network

Go language provides a luxurious network library and concurrency model, which makes Go language a very easy-to-use tool. Learning the Go language's network model can give you a better understanding of its concurrency model.

7. Trying to implement blocking IO in Go

The way Erlang handles IO is different from most languages. Its IO model is non-blocking. This is because the Erlang process It will actively give up the CPU when performing IO operations. However, in Go language, IO operations are blocking. Trying to implement blocking IO in Erlang in Go language can give you a better understanding of its IO model.

In short, it is not easy to switch Erlang to Go language. It requires you to fully understand the characteristics and working methods of these two different languages. Overcoming these challenges in practice will take some time and effort, but as a passionate and skilled software engineer, you will be able to successfully transition and take advantage of the best of both languages.
