Course Description
Overview
This Go Language Essentials course combines the ease of programming of an interpreted, dynamically typed language with the efficiency and safety of a statically typed, compiled language.If you are leveraging Go to create applications on the job or on your own, attending this course will help you understand how Go works, and immediately be more productive.
If you are building a team using Go, this will be a great opportunity to get your team on the same page and speaking the same language.
The materials and presentation focus on teaching students how to write clear and robust code to create real-world solutions. Innovative lab exercises and code samples are provided to reinforce skills and quickly master the topics.
Objectives
After completing the Go Language Essentials course, students will be able to:
- Learn the basic structural elements of a Go program
- Learn to use the basic types, aggregate types, reference types, and interfaces
- Learn error-handling strategies
- Learn to compose types and implement encapsulation
- Learn how to create a method (receiver function) on a struct
- Learn how and when to use pointers
- Learn how to use the interface type to enforce a contract
- Learn how and when to use anonymous functions
- Learn how to send and receive data using channels
- Learn concurrency and synchronization techniques
- And much more!
