Go / Golang Crash Course

description
In this crash course we will get started with the Go programming language. There is no prior knowledge of Go required. We will setup a workspace and look at fundamentals like variables, slices, conditionals, maps, structs and more Workspace - 1:35 Hello World - 7:37 Variable & Types - 11:18 Packages - 21:43 Functions - 26:25 Arrays / Slices - 29:35 Conditionals - 35:15 Loops - 41:30 Maps - 47:27 Range - 0:53:25 Pointers - 1:01:23 Closures - 1:06:48 Structs - 1:10:54 Interfaces - 1:26:53 Web - 1:33:29 Sponsor: DevMountain Bootcamp https://goo.gl/6q0dEa Code: https://github.com/bradtraversy/go_crash_course (I plan on tidying the code up later) Doc: https://golang.org/doc/code.html 💖 Become a Patron: Show support & get perks! http://www.patreon.com/traversymedia Website & Udemy Courses http://www.traversymedia.com Follow Traversy Media: https://www.facebook.com/traversymedia https://www.twitter.com/traversymedia https://www.instagram.com/traversymedia
