GoLang Fundamentals

Objectives:

The objective of the GoLang Fundamentals course is to provide participants with a comprehensive understanding of the Go programming language ecosystem. By the end of the course, participants will be equipped with the necessary knowledge and skills to begin their journey in Go development, including syntax, data structures, concurrency, testing, documentation, and web development.

Prerequisites:

Participants are expected to have some prior programming experience in another language, such as Java, Python, or similar. Familiarity with basic programming concepts such as variables, loops, conditionals, and functions is recommended.
