Go Programming Language
                     Go Programming 
Language: 
Explained Simply!
Why Golang?
• To make processors highly performant Hardware 
manufacturers are adding more and more cores to the 
processors.
•  Since data centers are running on such processors the 
number of cores will increase over the years. 
• However, addition of cores has physical limitations and 
software optimizations are required.
• Thus, languages should support concurrency easily and 
they should be scalable with increased number of cores.
• Go was developed with the express purpose of scalability 
and concurrency.
Following are some of the features of Golang, 
which make it most suitable for modern 
computing needs:
Multithreading
Go has lightweight threads that

execute asynchronously thus

Golang. 
These channels make the order of

performance.
ensuring that it executes safely. 
Language Design
• Go programming language is easy to understand and 
readable.
•  It minimizes dependencies of code. For instance, Golang 
doesn't have Classes, Constructor, Inheritance, Generics 
and Exception. 
• As a result, dependency management is good due to its 
object-oriented support. 
• Data structures in Golang such as slice and struct provide a 
convenient way of storing elements. This makes it easier for 
developers to create neat code which is easy to create and 
most importantly easy to maintain with short compile 
time.
Package Management
• Golang Package Management allows 
developers to utilize the functionality 
of other files.
• This removes the requirement of 
adding header files to every program.
• It also facilitates Remote Package 
Management. Improved Package 
Management provides improved 
features of the application.
Powerful standard library
• Go’s powerful Standard library has been segmented into 
packages. These packages provide a wide range of 
functions.
•  Some of these packages are Compression Packages, String 
related packages, collection packages, graphics packages, 
Mathematics packages and even miscellaneous packages. 
• This kind of library support helps developers to quickly 
compile functionality rich applications.
Static Typing
• It is an open source programming language which is 
statically typed and explicit.
•  However, though it is statically typed its syntax follows 
patterns which are similar to those of Dynamic languages. 
• As a result, Golang combines hardware efficiency with 
software efficiency. 
• Thus Go programs implement functionality with less 
machine code while ensuring that written code executes as 
quickly as possible.
Testing Support
• Go has inbuilt testing support. It allows programmers to test 
parallelly with writing code. 
• Further, package testing allows automated testing for Go packages. 
This is used along with the “go test” command, which automates the 
execution of any function of the form. 
• Go language also features automated garbage collector. Such testing 
and garbage collection help build error-free and bug-free applications 
that perform optimally at the client end.
Platform Independent
• Go supports platform 
independence. 
• Its code is compiled and 
converted to binary form 
right away such that it is 
so small that it does not 
require any dependency. 
• Such source code can be 
compiled on any 
operating system, 
platform, server or 
application. This brings 
about cost efficacy for the 
client.
