# PROGRAMMER'S ROADMAP
|
||||||
|
|
||||||
|
Hi!
|
||||||
|
|
||||||
|
If you're an experienced developer, you may want to watch only the following lectures. If you follow this roadmap, you will need to watch about 50 lectures instead of 180 lectures.
|
||||||
|
|
||||||
|
This course starts from the most basics than advances toward the end, step by step. So, the complexity of the topics increases on each level. I've intentionally designed it so to make it easy for everyone.
|
||||||
|
|
||||||
|
If you think some of the topics are easy for you, then watch the recap lectures, take the quizzes and exercises, and even skip the lectures in that section altogether, you can always come back to them later.
|
||||||
|
|
||||||
|
Enjoy!
|
||||||
|

# BONUS: Why should you learn Go?
|
||||||
|
|
||||||
|
**In summary:** Go is easy as Python and Javascript , and it's as fast as C/C++. It's more enjoyable to work with Go than C/C++. You can go low-level, or you can stay high-level.
|
||||||
|
|
||||||
|
## What Go is used for?
|
||||||
|
|
||||||
|
Go is used mostly by web companies: Google, Facebook, Twitter, Uber, Apple, Dropbox, Soundcloud, Medium, Mozilla Firefox, Github, Docker, Kubernetes, and Heroku.
|
||||||
|
|
||||||
|
**Go is best for:** Cross-Platform Command-line Tools, Distributed Network Applications, Cloud technologies like Microservices and Serverless, Web APIs, Database Engines, Big-Data Processing Pipelines, Embedded Development, and so on.
|
||||||
|
|
||||||
|
**Go is not best for (but doable):** Desktop Apps, Writing Operating Systems, Kernel Drivers, Game Development, etc.
|
||||||
|
|
||||||
|
## Who Designed Go?
|
||||||
|
|
||||||
|
Go designed by one of the most influential people in the industry:
|
||||||
|
|
||||||
|
* Unix: Ken Thompson
|
||||||
|
* UTF-8, Plan 9: Rob Pike
|
||||||
|
* Hotspot JVM (Java Virtual Machine): Robert Griesemer
|
||||||
|
|
||||||
|
## HOW MUCH CAN YOU EARN?

## [From Eight years of Go post](https://blog.golang.org/8years):
|
||||||
|
|
||||||
|
> Today, **every single cloud company has critical components of their cloud infrastructure implemented in Go** including Google Cloud, AWS, Microsoft Azure, Heroku, and many others. Go is a key part of cloud companies like Alibaba, Cloudflare, and Dropbox. Go is a critical part of open infrastructure including Kubernetes, Cloud Foundry, Openshift, NATS, Docker, Istio, Etcd, Consul, Juju, and many more. Companies are increasingly choosing Go, to build cloud infrastructure solutions.

# ROADMAP FOR EXPERIENCED DEVELOPERS
|
|
||||||
|
|
||||||
Hi!
|
|
||||||
|
|
||||||
If you're an experienced developer, you might want to follow this roadmap while taking this course.
|
|
||||||
|
|
||||||
This course starts from the most basics than advances toward the end, step by step. So, the complexity of the topics increases on each step. I've intentionally designed it so to make it easy for everyone.
|
|
||||||
|
|
||||||
If you think some of the topics are easy for you, then watch the recap lectures and skip the lectures in that section altogether, you can always come back to them later.
|
|
||||||
|
|
||||||
BTW, if you're also wondering about why should you learn Go, then scroll down to the bottom of this article.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## Basic Configuration
|
|
||||||
|
|
||||||
1. **Git clone the repo**
|
|
||||||
https://github.com/inancgumus/learngo
|
|
||||||
|
|
||||||
2. Read **"Side Note About Go Modules"** part right after the outline below.
|
|
||||||
1. If you also want to learn about GOPATH, watch: "Learn about GOPATH and Go directory structure" lecture
|
|
||||||
|
|
||||||
3. You might want to **increase the video speed**.
|
|
||||||
1. If you don't know how, [here](https://support.udemy.com/hc/en-us/articles/229231247-Change-the-Video-Speed)'s how you can do that.

## SIDE-NOTE ABOUT GO MODULES
|
|
||||||
|
|
||||||
Since Go 1.11, there's a new feature called Go Modules (_it was known as vgo before_).
|
|
||||||
|
|
||||||
With Go Modules, you are not required to put your source code files under $GOPATH anymore. You can put them in any directory that you want.
|
|
||||||
|
|
||||||
If you're a power user and want to try this **experimental feature**, just put your programs in a directory outside of `$GOPATH` (this is very important). And then run this to initialize your module:
|
|
||||||
|
|
||||||
`go mod init [module-name]`
|
|
||||||
|
|
||||||
Afterward, while in this directory, Go assumes that it's like you're under your GOPATH. However, you'll be under your module's directory. You can create as many modules as you want. However, keep it simple and use only one module for now.
|
|
||||||
|
|
||||||
### EXAMPLE:
|
|
||||||
|
|
||||||
1. Let's say that my module directory is under: `~/Desktop/go`
|
|
||||||
2. Also, my github.com username is: `inancgumus`
|
|
||||||
3. And, I have a program called: `hello`
|
|
||||||
4. So, I put my hello program under: `~/Desktop/go/hello`
|
|
||||||
5. Then, while under `~/Desktop/go` I would call mod init like this:
|
|
||||||
|
|
||||||
`go mod init github.com/inancgumus`
|
|
||||||
|
|
||||||
6. So, if I want to build my program, I'll go into `~/Desktop/go/hello`
|
|
||||||
7. Moreover, I can use usual go build and go run commands there.
|
|
||||||
8. By doing so, I've created a single module for all my projects. As I've said, you can also create separate modules for each of your projects, like this:
|
|
||||||
|
|
||||||
`go mod init github.com/inancgumus/hello`
|
|
||||||
|
|
||||||

## Why you should learn Go?
|
|
||||||
|
|
||||||
If you're curious about why you should learn Go, then check out this summary here.
|
|
||||||
|
|
||||||
**In summary:** Go is easy as Python and Javascript and it's as fast as C/C++. It's more enjoyable to work with Go than C/C++. You can go low-level, or you can stay high-level.
|
|
||||||
|
|
||||||
### WHAT GO IS USED FOR?
|
|
||||||
|
|
||||||
Go is used mostly by web companies: Google, Facebook, Twitter, Uber, Apple, Dropbox, Soundcloud, Medium, Mozilla Firefox, Github, Docker, Kubernetes, and Heroku.
|
|
||||||
|
|
||||||
**Go is best for:** Cross-Platform Command-line Tools, Distributed Network Applications, Cloud technologies like Microservices and Serverless, Web APIs, Database Engines, Big-Data Processing Pipelines, Embedded Development, and so on.
|
|
||||||
|
|
||||||
**Go is not best for (but doable):** Desktop Apps, Writing Operating Systems, Kernel Drivers, Game Development, etc.
|
|
||||||
|
|
||||||
### WHO DESIGNED GO?
|
|
||||||
|
|
||||||
Go designed by one of the most influential people in the industry:
|
|
||||||
|
|
||||||
* Unix: Ken Thompson
|
|
||||||
* UTF-8, Plan 9: Rob Pike
|
|
||||||
* Hotspot JVM (Java Virtual Machine): Robert Griesemer
|
|
||||||
|
|
||||||

### [From Eight years of Go post](https://blog.golang.org/8years):
|
|
||||||
|
|
||||||
> Today, **every single cloud company has critical components of their cloud infrastructure implemented in Go** including Google Cloud, AWS, Microsoft Azure, Heroku, and many others. Go is a key part of cloud companies like Alibaba, Cloudflare, and Dropbox. Go is a critical part of open infrastructure including Kubernetes, Cloud Foundry, Openshift, NATS, Docker, Istio, Etcd, Consul, Juju and many more. Companies are increasingly choosing Go, to build cloud infrastructure solutions.
