Golang Developer

Golang (also called Go) is a statically typed, compiled programming language build for industry professionals and it was launched by Google in 2009. The language combines the efficiency of C++ efficiency and the readability of Python, Which makes Golang popular between developers now days.

The Go programming language is used by Golang developers to create websites and apps, which can optimize the entire system. Go offers subprograms to run their actions simultaneously with the help of Concurrency. Various programming languages implement concurrency but Golang does this with a twist. It doesn’t follow the threading model for concurrency; it follows the Communicating Sequential Processes(CSP) model. Working with Go and its full range of tools and frameworks is part of a Golang developer’s job description. Most Go programmers also test and debug their code.

Learn the basics of Go

To become a Golang developer, you must have a knowledge of the language and its syntax. You can either install the language and teach yourself, or you can enroll in an online course to help you get started. A decent learning route for Go will look something like this:

1. Filenames, keywords, identifiers
2. Operators, types, functions, and constants
3. Pointers, structures, methods
4. Maps, arrays, slices
5. Go CLI
6. Interface
7. Error handling
8. Goroutine, Channel, Buffer, Concurrency
9. Panic, Defer, Error handling, Recover
10. Go design patterns

Understanding of Go libraries and other Go tools

Once you have the basics of the language down, you should move onto the add-on(external packages) libraries and tools that make Go easier to use. Most companies will expect that you have experience with:

• Go dependency management tools
• Semantic versioning
• Scripts and repositories
• Go Standard libraries
• SQL fundamentals
• GIT
• Basic authentication
• HTTP/HTTPS
• Web frameworks and routers
• Relational databases (PostgreSQL)

Learn testing with go

As a Go developer, you’ll be building products for the real-world, so you need to test your products for usability and reliability:

• Unit testing
• Integration testing
• Behavior testing
• E2E testing

Go patterns

Go offers similar design patterns to other languages that fall under these general categories:

• Structural
• Creational
• Behavioral
• Concurrency
• Stability
