A queue is an abstract data type (ADT) that follows the first-in, first-out protocol. Think of standing in a line for purchasing an item. The first person on the line is the first one that exits the line and the last person on the line is the last one to exit.

There are different ways we can create a queue. One way is through using an array. Another is through a linked list where each “person in the line” is a node.

Some suggested terms:

• First in, first-out (FIFO) protocol
• enqueue
• dequeue
• peek

When new features are added to an existing program, it’s important to ensure that previous functionality has not been affected. This is where regression testing comes into play.



While some use manual testing, there are many automated regression testing tools out there. It’s also suggested that this piece incorporates common techniques for regression testing.

Object-oriented programming (OOP) is a programming paradigm that revolves around creating objects with a single responsibility. By following the SOLID principles when using OOP, we can create better programs with reusable, testable, and maintainable code.

Some suggested terms:

• Inheritance
• Encapsulation
• Polymorphism
• Data abstraction
• Single-responsibility
• Open-closed
• Liskov substitution
• Interface segregation
• Dependency inversion

One of the four pillars of object-oriented programming (OOP), inheritance supports reusable code. When a class inherits from another class (super or parent), it takes on properties and methods that were declared in the superclass.

A hands-on tutorial in web scraping using the popular library called Puppeteer.

Write a tutorial article that teaches readers how to build a small full-stack application with the Ruby on Rails framework. This should include the following:

• A prerequisite section detailing what competencies and technologies the readers will need to complete the tutorial.
• Building a back-end with Active Record models, Action Controllers, and Routing.
• Designing a front-end with Action View.

You can be as creative with the idea for the application as you'd like but it should be relatively small (like a minimum viable product). Please keep the content original 👍🏻.

Problem

I noticed that the screenshots in my article did not appear

Solution

Link the images

A slug is what you see at the end of a URL. For some sites like Pinterest, when you click to access a particular item (in our example, it’s a pin), the URL will read something like https://www.pinterest.com/pin/914862416083562/. This long number is probably an identifier for the pin as it’s retrieved from the database, but it holds little value in representing the pin image contents.



When slugs are fine-tuned, they benefit SEO (Search Engine Ranking). Users can find relevant content they want to read, and websites get more traffic. It’s a win-win!

I'm creating this issue in order to establish a set of steps for the retrieval of ccId.

Currently, I've used the Redux dev tools to access the state of the website and then follow the following path in the global state tree:

{
  ccId: currentUser.id
}

Is there any other way to retrieve the ccId from the website?

And furthermore these steps need to be added to the contribution guidelines in order to streamline this process for other UGC members.
