Go Concurrency First Steps

Concurrency fundamentals and patterns in Go

Topic: Software Development
Mofi Rahman

Concurrency is a hard concept to grasp. It’s also quite difficult for developers to properly implement without extensive knowledge and practice. But it’s necessary for certain problems where speed is of the essence.

Go is known for its simple-to-use concurrency primitives. (Unlike in many other languages, concurrent execution was a day-0 implementation in Go.) Go concurrency allows you to easily write concurrent programs and scale your applications.

Join expert Mofi Rahman for an introduction to Go concurrency. In just three hours, you’ll learn a set of basic patterns to use concurrency in your everyday Go projects.

What you'll learn-and how you can apply it

By the end of this live online course, you’ll understand:

  • How Go concurrency works
  • How to write concurrent Go programs
  • Common Go concurrency patterns

And you’ll be able to:

  • Use Go concurrency for your project
  • Avoid common pitfalls and mistakes in concurrent algorithms

This training course is for you because...

  • You want to understand Go concurrency and write concurrent applications.
  • You want to make your applications faster.

Prerequisites

  • A computer with Go 1.13+ installed and configured (Optional: Install an editor with Go support—VS Code + the Go extension, for example.)
  • A working knowledge of Go
  • Familiarity working in a terminal
