Download Go 1.18 and Explore Its New Features with Tutorials and Examples
How to Download Go 1.18
Go is a popular open source programming language that is designed for simplicity, concurrency, and performance. It is widely used for developing web applications, microservices, cloud-native software, and more.
The latest release of Go, version 1.18, is a significant release that includes new features, performance improvements, and the biggest change ever to the language: generics. Generics allow you to write code that can handle multiple types without repetition or type assertions. Other new features include fuzzing, which is a technique for finding bugs in your code by feeding it random inputs; workspaces, which make it easier to work with multiple modules; and CPU performance improvements of up to 20% on some architectures.
