Go was developed by a team of engineers at Google, primarily Robert Griesemer, Rob Pike, and Ken Thompson, who released it publicly in 2009.
The primary motivation behind Go’s creation was to address the limitations the team observed in other programming languages, especially when building large, scalable systems at Google. Many of these limitations were based upon unique circumstances that Google faces with dealing with such large data sets. At the time, Google relied heavily on languages like C++ and Java, which were powerful but had limitations in terms of compilation time, complexity, and ease of use.
The team had a few core goals for Go:
- Fast Compilation: C++ projects at Google were becoming enormous, leading to long compile times that slowed down the development process. The Go team wanted a language that could compile quickly, almost as fast as an interpreted language like Python, without sacrificing performance.
- Concurrency: The team aimed to make concurrency easier and more efficient. Since Google’s applications often needed to handle massive numbers of simultaneous requests, Go’s creators prioritized a concurrency model that would work well with multicore processors. Goroutines and channels were designed to enable lightweight, efficient concurrent programming.
- Simplicity and Ease of Use: Many modern programming languages had grown very complex over time, which the Go team felt added unnecessary mental overhead. Go was designed to be simple, with minimal syntax and a focus on readability, making it easier for both new developers and large development teams to work together on codebases. They emphasized reducing complexity and making the language feel uncluttered, in contrast to languages with extensive feature sets like C++.
- Safety and Robustness: Go was built with memory safety in mind, offering garbage collection to automate memory management and reduce common errors associated with memory leaks and pointer manipulation. However, it was also built to provide better performance than languages with similar memory safety features, like Java.
- Efficient Standard Library: The Go team wanted a language that came with a comprehensive standard library that would meet most of the common needs in web and systems programming out of the box, from networking to file handling.
However, as with any design, sometimes compromises must be made. For example, here are somethings which were left out of Go. Often this was for clarity sake, and/or to simplify things, so that the language was easier to use, and faster to compile and execute.
- Go does not have sub-classes nor does it support inheritance. This is an unusual approach to object-oriented programming.
- There are no constructors or destructors.
- No control structures associated with error handling, similar to the try-catch-finally paradigm.
- It does not have pointer arithmetic,
- Nor does it have implicit numeric conversions.
In summary, Go was developed by experienced engineers who saw a need for a language that combined the performance of compiled languages like C and C++ with the simplicity and productivity of scripting languages like Python. By addressing these pain points, they created Go to be a practical tool for modern software engineering, particularly for large-scale, concurrent, and cloud-based applications.
