Go Programming Language

Go Programming Language was developed by Google in the year of 2007. Its syntax is the same as the C programming language and is statically typed. It provides features like dynamic-typing capability, garbage collection, type safety, many other built-in types like key-value maps and variable-length arrays. Go also provides a rich standard library. This programming language is utilized in some of Google’s production systems. Go has various salient features. It supports and adopts the environment patterns similar to its dynamic languages feature. Go language has a faster compilation time. It provides inbuilt concurrency support and lightweight processes through Go routines, select statements, and channels. 

Go Programs are simple, concise, and safe. It supports type embedding and interfaces. Without much involvement of the external dependencies, it can produce the statically linked native binaries. Some of the features in Go Programming Language were deliberately dropped to keep the language simple and concise. Some of the commonly available features that are ignored include support for inheritance, operator or method overloading, pointer arithmetic, circular dependencies among packages, assertions, and generic programming. All these features are omitted to enhance the language in other lacking areas. Hence, it is one of the faster processing programming languages related to networks. 

In a Go program, the lines of code may vary, and it can range from 4 lines to millions of lines. These programs can be written in the text editors like vi or vim with the ‘.go’ file extension. Let us look into the simple exam of the Go program. You will first need to understand the structure of the Go program. It basically consists of: Package Declaration, Importing of Packages, Functions, Variables, Statements, Expressions, and Comments(if any).

Here is the simple “Hello World” Go program.

package main

Import “fmt”

Func main()

{

fmt.Println(“Hello World! Welcome to Go Programming World)

}

In the above program, the first line defines the package name in which this program should be executed. It is the mandatory statement as it determines in which package the program lies. The starting point of the Go program is the main package, and each package has a name and path associated with it. The import of ‘fmt’ in the following line is a processor command that informs the Go compiler to include the files related to the fmt package. The func main() in the next line is the main function from where the program execution begins. The compiler ignores the comment lines as the main purpose of these lines is for the programmers or the reader’s understanding. The Println() function in the next line is the function in Go that allows one to print the desired output on the console. This function is exported from the fmt package, which will enable you to see the outcome on the screen. The capital letter ‘P’ of Println plays an essential role in Go Programming Language. The functions are exported in the Go language when their name starts with a capital letter. 

Go programming Languages became popular with their few advantages compared to other programming languages. It, to an extent, sorts the problems related to compiling runtime errors, dependencies, and speed. Go has climbed up the development ladder by tackling these features, which are the problematic areas for the other languages. Below is the list of benefits of Go Programming Languages.

• The famous language is written by the Google associates and is well-known for its contribution to the JVM, Unix, C, etc. This language was designed to sort out the past problems faced and lead to future challenges.

• Go Programming Language is easy to learn. People are for sure looking forward to diving into the Go’s new features and the comfort level it provides. If you want your fellow developers to enjoy the ease of work, you can surely recommend the Go programming language. Go has a similar syntax to the other programming languages and looks almost similar, and its documentation is also simpler to follow. Using Go writing a simple command line and the HTTP server is now a piece of cake.

• Go Programming Language is an open-source language that allows you to achieve concurrency that is easy and traceable. The developers are able to free the network and hardware faster as the requests are attended to and solved at a quicker pace.   

• The one more attractive feature of Go Programming Languages is that it comes with in-built testing tools. While dealing with network-oriented work, testing plays a vital role in it. It is also a most loved fact by developers that language comes with the in-built testing tools and the most straightforward API. This makes the job simpler and allows you to test and execute the code faster and release your code with renowned confidence. Parallelly the facility of testing and keeping track of your product in the market is also available.
