GOLANG

Overview

This course introduces learners to the Go programming language, starting with its fundamentals such as variables, data types, control flow, and functions. It progresses into core concepts like structs, methods, interfaces, and pointers. Learners will also explore concurrency mechanisms including goroutines and channels, along with building REST APIs and working with files and JSON. A mini project on an online quiz system ties together key concepts for practical application.

Objectives

• Understand Go's syntax, data types, variables, and control structures through hands-on coding exercises.
• Implement concurrency patterns using goroutines, channels, and synchronization primitives.
• Build and deploy REST APIs with Go, handling requests, responses, and CRUD operations.

Key topics

• Introduction to Go and Setting Up the Environment
• Functions and Control Flow in Go
• Concurrency with Goroutines and Channels
• REST API Development with Go
• Structs, Methods, and Interfaces
• Error Handling and File Operations

Expected outcomes

• Develop and run basic Go programs, including interactive calculators and data processing tools.
• Create structured applications using structs, methods, interfaces, and error handling.
• Design and implement concurrent programs and RESTful web services in Go.
