Let's actually write some code
Following is a simple program which takes input from the user and displays a greeting.
1 | ( ) ( |
When this code is run, it prompts the user for their name and displays a greeting.
Key points for studying
• Set small goals: Let's start with a simple program, such as one that displays "Hello, World!".
• Get your hands dirtyWriting code helps you understand it better.
• Don't be afraid to make errors: Errors are learning opportunities.
• Leverage the community: Exchange information on Q&A sites and forums.
summary
Go is an easy-to-learn and highly practical programming language for beginners. By understanding the basic grammar and actually writing code, you can steadily acquire skills.
Use this article as a reference to get started on learning Go. Continuous learning and practice will help you improve your programming skills.
