Go Language And Its Environment Set Up

Go Language And Its Environment Set Up
Features of Go language


Go is a programming language, which is designed by Google(2007).


Why it is introduced?

1. Limitations in the hardware.

The performance of the system has to be increased. Using a large number of hardware parts like the transistor and the processor, which is not possible. When one of them increases the cost will increase or the performance will reduce.


2. The code is easy to maintain

The code written with Go language has a simple and understandable syntax. These features help to maintain the code easily.


Features of Go language

  • Open-source.
  • Used at the backend.
  • Made of packages
  • Performance is greater.
  • Has garbage collection.
  • Easy to read the code.
  • Throughput is better.
  • Has garbage collection.

How to set up the environment to start coding in Go language.

Initially go to The Go Programming Language (golang.org) and download Go language by clicking the relevant link(select the correct Operating System).


What is Go language and how to set up the environment?
Download Go


Click on the below icon in the location where it is installed to start the downloading process.

After finishing the installation you can check the version of the go language by typing "go --version" in the command line.

After the installation, you can start coding. The file extension is .go.

Let us learn how to code hello world using the syntax in go. I am using VS Code as the IDEA. So I will explain the code implementation using the VS Code.

Tip: VS Code has an extension to give suggestions when you code using the Go language.

Now it is time to execute the code.


How to run a .go file?


How to run a .go file
Hello World! in Go language


Go to the terminal in the VS Code and run the following command.

go run file_name


Example:

Let us assume that I am having a main folder as coding. Inside the coding folder, there is a file name called hello.go where the hello world code snippet is written. 


How to set up the environment to start coding in Go language.
folder set up with .go file

I will run the .go file as shown below 

go run hello.go

How to run .go file in terminal


The terminal of the VS Code shows the output as Hello World!.


Explanation about the code

  • The package which is used to run a program written in Go language is main.
  • Packages are imported to the program with the import keyword.
  • fmt is a package and it is known as the format. fmt is used to provide input and output functions.
  • The function main is defined as func main().
  • It is possible to access functions from packages where the first letter of the exported name has to be capitalized. Example:  fmt.Println()


Conclusion

This blog was written to give an understanding of the Go language for beginners and to know the reason to have it as the programming language. In the future post let us learn more about the Go language. 

Thank you so much for reading my blog. 

I believe this blog will help you to start learning about the Go language where I have guided you to install the Go Language. Now start coding.

7 Programming Tips For Developers (Beginners)

Beginners initially get scared when started coding. This blog is to help beginners. It will help to avoid the fear and make you more confident. 1. Code daily. “Practice makes a man perfect ” Practicing coding every day helps to overcome the fear of coding. It helps to improve our coding skills and build confidence step by step. Do not get demotivated at the initial stages. During the initial stages of coding, it takes more time to implement a function, takes many days to solve an error. It is totally fine. Every developer faced the same issue at the beginning, therefore you are not the first person to face this problem, and get stressed. Everything will be ok when you start coding continuously. When you start coding, you identify the mistakes and solve the problem by searching through the internet. You try to resolve the errors by yourself. When the problem is not solved, you can get help from other developers or colleagues. There are many resources to get help through the interne...

What are SOLID Principles? Explained with OOP Concepts.

 What are SOLID Principles? Explained with OOP Concepts. SOLID Principles Software developers implement codes to meet the users' requirements and satisfy the clients. Some principles have to follow by software developers to enhance their code writing skills. The SOLID principles have considerable responsibility to guide the software developers, to make the software design by improving the code quality.  An American software engineer named Robert C.Martin created this principle. Why do we need SOLID principles? Advantages of using SOLID Principles. Make the code more understandable and readable. Make the code snippet as simple as possible by reducing the complexity. Make the lines of codes flexible. Therefore the code snippets are updatable or modifiable when required. To maintain the software codes easily. To reduce the dependencies. To make the code testable. To implement the code.  Solid principles have five(5) principles. The name is created by considering the first fi...

Microservices

The software architecture is responsible for organizing the software structures (components, interactions of the components with each other, environment, principles used to design the software product). A software architect is a person who is responsible for design architecture for a particular application.  The software architect’s functions are, 1. Identify the system’s structure. 2. Identify the use-cases relevant to different scenarios. 3. Organize the user requirements (functional and non-functional) There are many software architectures. When developing an application, the most suitable architecture has to be selected. Fault selection of architecture leads to the failure of an application where the time and allocated budget will become useless. Micro-services  Micro-services is an architecture, which has Service Oriented Architecture (SOA). SOA has an application scope. It is suitable for a large-scale application. The micro-service architecture uses to develop an applic...
