Why use Golang

Go also known as Golang was Created by Google in 2007 and open source in 2009

Why use Go? Purpose? and Different from other languages?

Background:

• Infrastructure changes in multicore process, cloud infrastructure, and clustering. Providing scale, dynamic infrastructure and capacity.
• Applications could be written to do multiple tasks at once. For example, cloud drive managers and video websites allowing multiple tasks going for users
• Challenges of multithreading
  • Modifying the same data source
  • Concurrency - conflict management of resources

Use Case of Go

It is good for applications that need to perform well and run on scaled, distributed systems.

Go was designed to run on multiple cores and concurrent applications. It works well for server side and back-end software, for example docker, HashiCorp Vault, Kubernetes, Cockroach DB, and command line applications.

Characteristics and Use Cases

Go tries to combine simple and readable syntax like Python with efficiency and safety of a statically type language like C++.

Programs usually have fast build, start up and run time and require less computer resources. It compiles to a binary that can run on different operating systems.

Setting up a Development environment

For an integrated development environment, can use GoLand from JetBrains with project management, compilation, completion, and other features.

Install the Go compiler. If using GoLand, selecting the SDK version will automatically install it.

To run source in GoLand, press the run button or use terminal.

Concepts and Syntax

For syntax and go commands for building and running programs, see Golang Snippets - Golang Snippets

Packages are a set of source files available for reuse for application functionality. They can be browsed at pkg.go.dev.

Use the net/http import, HTTP functionality can be added to the application.
