What is Golang and how to install it.

                           What is Golang?

Golang, also popularly known as Go is open source statically designed and procedural programming language developed by three Google engineers Robert Griesemer, Rob Pike, and Ken Thompson.

Syntax of golang is very much similar to c programming language. it is a very efficient programming language because it has features like memory safety, garbage collection, structural typing.

=>More about features.

Memory safety - Memory safety is the state of being protected from various software bugs and security vulnerabilities when dealing with memory access.

Garbage collection - Garbage collection is the systematic recovery of pooled computer storage that is being used by a program when that program no longer needs the storage.

Structural typing- In structural typing, an element is considered to be compatible with another if, for each feature within the second element's type,  the corresponding and identical feature exists in the first element's type.

   Here type meaning constructing variables, expression, and functions.

Concurrency - Golang has great concurrency. You don’t deal with threads but rather create cheap goroutines which are simple to make and manage. Goroutines allow you to distribute the load across all of your CPU without worrying on how to manage it all.

What makes golang different from other programming languages.

•  it is much more productive than other programming languages.              
•  Go is a relatively simple language and found it easy to pick up and get started with                                                                                                

      And the above feature provide edge to golang over the other programming languages.
