About this course

WHY I WROTE THIS COURSE

Go is a programming language that combines the advantages of static typing with the flexibility of dynamic typing. Its simplicity and prototyping capabilities make it an excellent choice for building command-line tools. It also offers features such as type safety, cross-compilation, testing, and benchmarking, enabling developers to handle complex scenarios. You’ll start by learning the foundations in Go’s fundamental syntax and progressively delve into advanced concepts. Then, you’ll learn to develop various command-line applications that can automate tasks, process data, parse logs, interact with network services and fulfill system requirements. In addition, the course also covers different testing and benchmarking techniques to ensure the speed and reliability of programs. After taking this course, you’ll be able to automate your work and enhance productivity. You’ll also be able to utilize the Go programming language to develop robust, cross-platform, efficient, and maintainable CLI applications.

You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it.
