Racket is a general-purpose, multi-paradigm programming language based on the Scheme dialect of Lisp. It is designed to be a platform for language creation, experimentation, and research, and is widely used in computer science education. Racket provides a rich set of tools for creating new programming languages, including a macro system, a module system, and support for language-oriented programming. It also includes a large standard library and supports a variety of programming paradigms, including functional, object-oriented, and logic programming. Racket is available under the MIT License and runs on a variety of platforms, including Windows, macOS, and Linux.
Here are some of the key features of the Racket programming language:
Language-oriented programming: Racket provides a platform for creating and experimenting with new programming languages, thanks to its extensive support for language-oriented programming.
Multi-paradigm: Racket supports multiple programming paradigms, including functional, object-oriented, and logic programming.
Powerful macro system: Racket's macro system allows programmers to define new syntactic forms and extend the language in powerful ways.
Extensive standard library: Racket includes a large standard library that provides a wide range of functionality, including support for networking, file I/O, and GUI programming.
Dynamic compilation: Racket's dynamic compilation provides fast startup times and efficient execution of code.
Cross-platform: Racket runs on multiple platforms, including Windows, macOS, and Linux.
Overall, Racket's combination of language-oriented programming, multi-paradigm support, powerful macro system, extensive standard library, dynamic compilation, and cross-platform compatibility make it a robust and versatile programming language.
To choose a Region follow the below step:
1. Sign in to the AWS Management Console.
2. Choose a service to go to that service's console.
3. In the navigation bar, choose the name of the currently displayed Region. Then choose the Region to which you want to switch.
Step instructions for how to assess and monitor the health and proper function of the application:
1. Navigate to your Amazon EC2 console and verify that you're in the correct region.
2. Choose Instance and select your launched instance.
3. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.
To verify the installation, follow the below instructions
Step 1. Connect to SSH:
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
In the navigation pane, choose Instances.
Select the instance and choose Connect.
Choose SSH Client
Copy the SSH command and paste it into the terminal.
ssh admin@publicIP -i [Path of key pair file]
If it shows an access denied message run the following command, then run the above command again to connect via ssh.
chmod 400 [Path of key pair file]
Once launched in the Amazon EC2 Service, please connect to the instance via an SSH client using the ec2-user with the key pair associated at launch. Once connected as the ec2-user user, you will be able to sudo to the root user
Step 2. Verify the installation:
Follow the steps to verify the Racket installation
1. Login with ssh
2. Type the below command to check the version
3. To check the version :
How to use Racket in the terminal:
1. After connecting with ssh write the below command:
sudo nano HelloWorld.rkt
3. Paste the following code into the file:
#lang racket (displayln "Hello, World!")
2. After that use the below command :
The output "Hello, World!" should appear in your terminal. That's it! You have successfully printed "Hello, World" using Racket in the terminal.
4. After using the above command then verify written the below command mentioned below image:
To monitor and assess application functions:-
a. Navigate to your Amazon EC2 console and verify that you're in the correct region.
b. Choose Instances and select your launched instance.
c. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.
