Are you ready to dive deeper into Go? Let’s get started.
Before reading this blog, you have seen the Go’s history, characteristics, and distinctions. Now we’ll see how to run the projects.
Golang is a proficient programme language in C/C++/Java.Though its syntax is as easy as Python/Perl. It’s very accommodating for both humans and processors. So, In this comprehension, you will learn basic baby steps towards the beginning of Golang with suitable examples.
Setting up the environment for GO
There are a lot of people around us who at first face challenges with setting up the environment. After reading this article you can resolve your issue.
Under this part, we will witness how to set a basic environment for code to run, build and do a compilation of all the Go Programming language Projects.
Hence, To begin the whole procedure here are some following steps mentioned below –
- The first step will be to download Go before you’re able to create and run Go programmes.
- The Second step – After the successful Installation of Go, You need to have a code editor named visual code installation. However, there are several platforms accessible for code changes. But one of the greatest connections is Visual Studio Code, which comes highly recommended.
- The Next step – Next step includes the configuration of VS code. The Golang version will be downloaded under the circumstances.
- The Last step – This part includes the writing of codes. It eventually is fun!!!
What is the procedure for the Installation of GO in Windows?
Some steps need to be followed to get install the Go programming language in Windows. So, This article will clear your understanding of how to install GO in Windows.
Another simple way to have these things done is you can simply hire golang developer and get your work done within a minute.
Mentioned below are the following steps:-
The First Step (Downloading Go) –
The first and foremost step is that you have to download the Golang. All version of golang is available and easily accessible on golang.org. You can just simply choose your version and download it accordingly.
The Next step (Install Go from.msi file) –
Right after the successful installation of Golang.The (.msi file) installer will begin.
Further, you simply have to click on the Go license agreement and then click yes. After kindly move to the next window.
Once you’re done with this, there’s already a value in the destination i.e. Go installation.
In the next step, To start the installation process, just simply click on install. Afterward, windows will ask you for administrative permission then you have to click yes.
After this, you have to accept the GO license agreement & simply have to click next.
Lastly, you have to complete the set-up and simply have to click on the finish.
Project – 1 (OI Hello World In GO)
After the successful installation of Go and setting up the environment. We’ll move further with our little project called OI’s Hello World. Initially, You have to create a new folder for this little new project called “Hello World”
Hence, various commands include under the Golang are as follows –
- Go run
- Go build
- Go install
- Go command
Under the Go run command, you just simply have to run the software. Afterward, you’ll be able to figure out the purpose of each command and a simple way to use them.
In short, it simply compiles & executes one or two files.
Let’s see the output in the visual studio code.
The Go build command is primarily used to make a simple compilation for packages that you have used in your projects.
Go build takes the actions & builds the files.
In short, It’s a simple compilation of go source code files.
Let’s see how it’ll look in VS code editor.
Go modules is a known to be an important dependency characteristic in Go. Generally, it helps to manage the Go files flexibly.
It is also called another way of collecting Go files, that is called Go modules.
A package is a collection of common source code files. In Golang, they don’t import the files, they import packages. It has nothing to do with files, they import files. They are not directories in the Golang language.
Even though there are multiple types of packages are as follows.
Go packages can be defined as a keeper as it keep one file under many files. Although each file of the package has to end with Go.
Although inside fo GO, There are two different types of packages i.e. Executable and Reusable etc. Thus, You can use the packages to accomplish multiple tasks.
Go functions simply mean a characteristic where they collectively perform a task. You can also sign them as the foundational or building block.
Functions are known to be one of the central & critical concepts of the Go programme language. However, The code of the function is always written as “func”.
Functions primarily help in creating modular code. They help in a situation where a big job can be disintegrated into small pieces of code. They also help in hiding implementation details from users.
Import statements are a very prominent step in running any project. The developers use import statements to have access to another package inside.
Thus, The importation of packages defines the statement at its best. The developers can easily access external packages & dependencies in the code
The New Project: Variable Declaration
Moving further on to see, another distinctive project by the Go Programme language.
The first & foremost step is that you have to create a new folder to get your new project started.
Variables are usually defined to specify characteristics & features. However, During the writing of our code, the term variable is described as “Var”.
In addition to this, Right after the successful data type insertion under the variables.
Now, Let’s see how it’ll look in VS Code Editor.
The Global & Local Variables
Moving further into variables, we have seen the two frictions within the concept. They are Global & local variables.
The term variable that is declared within a function is called a local variable. On the other hand, if the variable is declared outside the function is called a global variable. Global Variables can’t be specified within the functions. They’re outside them.
Now, Let’see how it’ll look in the Visual code editor of the golang programming language.
In the Go programme language, Constants are given complete security in respect of whatever value they hold within themselves. The Declaration of Constants has its own significance.
As you can simply see that in the given picture const name10 is assigned as “United Arab Emirates”
They can’t be amended as per any sort of essential requirements.
Const values can’t be changed once it’s been assigned previously.
A Simple Wind-up!
To conclude the above whole article, you have witnessed how to work on little projects such as hello world. However, After making you all understand the GO language. We hope to have given you a clear understanding of Go projects, functions, variables & packages, etc.
In fact, There is not even a single shortcut to learning about any programming language without learning, running, or diving deeper into code. After giving a 5 min read to this article, you’ll able to run code by your own self. Also, You can simply hire Golang Developer to get your functions run and your concepts clear. As we the popularity of GO language is getting popular with every passing minute.
