Go (programming language)

Go (often referred to as golang) is a programming language created at Google in 2009 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a compiled, statically typed language in the tradition of Algol and C, with garbage collection, limited structural typing, memory safety features and CSP-style concurrent programming features added. The compiler and other language tools originally developed by Google are all free and open source. (Wiki)

Golang Highlights

01. Compiled

02. Performant

03. Multiple-cores

04. Concurrency

05. Network

06. Statically typed language in the tradition of Algol and C

07. With garbage collection

08. Limited structural typing

09. Memory safety features

10. CSP-style concurrent programming

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

The major differences between Java and Golang are:

1. Go’s compilation speed is very fast as no VM is needed to execute Go program.
   
2. Go can return more than one value whereas Java can’t. Every time you need to create object as there is no pointer support in Java.
   
3. Garbage collection is pretty good in Golang.
   
4. Golang have goroutine in order to achieve multitasking.
   
5. A single thread in java takes more than 1 MB memory on heap whereas goroutine takes approx. 2 KB.
   
6. You need to extend class from Thread class or implements Runnable interface and need to put your logic in run() in java , but in Golang you just need to write go keyword before function definition so it will make that function as goroutine.
   
7. Also synchronization support is very good in golang.
   
8. Go’s interface is more flexible as there is no support for inheritance. Inheritance makes things more complex in bigger projects.
