Today, I started learning Go(Golang), and I want to note down some key concepts that I think are important to understand and remember.
Since this is based on my current understanding, there may be mistakes. If you notice any, please leave a comment, I would really appreciate your feedback.
When I was looking at backend developer job postings, I noticed that Go is frequently listed as a required or preferred programming language. This is true for both startups or well-established technology companies. That led me to a question: Why do so many developers choose Go for new projects?
After researching various resources and books, I found that Go has become increasingly popular because it addresses modern software development challenges.
When choosing a programming language for new project, there are usually trade-offs between development speed (such as Python), execution performance (such as C or C++) and team familiarity.
Go sits somewhere in the middle of these competing priorities by offering both rapid development and strong performance.
Here are some features that I believe contribute to Go's growth in the software industry.
- Concise syntax: Go has simple and concise syntax with relatively few keywords to learn. Because of this, new developers can become productive quickly and focus more in solving problems rather than learning complex language features.
- Fast compilation: Go's compiler is known for its speed. Instead of waiting a long time for a project compile, especially in large codebases, developers can build and test their applications quickly. This helps improve productivity and shortens the development feedback loop.
- Efficient Resource Utilization: Go can efficiently utilize modern hardware resources because it has built-in support for concurrency. Go provides gorountines, which are lightweight thread managed by the Go runtime. Goroutines requires significantly less memory than operating system threads, and it easy to create and manage. Go also provides channels, which allow goroutines to communicate safely. Channels helps reduce the complexity of sharing data between concurrent tasks and can prevent some common synchronization issues.
- Garbage Collection: Go includes a garbage collector, which automatically manages memory allocation and deallocation. This significantly reduces the risk of memory-related problems and allows developers to focus more on business logics. Although garbage collection introduces some runtime overhead, it is often acceptable trade-off for improved productivity and reliability. I once experienced application crashes in C++ due to management memory mistakes, so I personally find this trade-off worthwhile.
There are some of the main reasons I found while researching why Go has become popular in software industry. It combines ease of development, good performance and strong support for concurrent programing, making it a compelling choice for many backend systems or cloud-native applications.
If I have misunderstood anything or you have additional insights, please leave a comment. I would greatly appreciate for your feedback.
Thank you for taking the time to read my blog, and good luck on your learning journey!
