A code repository, also referred to as a code repo, is a place where developers can store, share and collaborate on the source code of a software project. Beyond the code itself, you can keep documentation, notes, web pages, and other items in your repository.

A library stores books, a compilation of information and resources, that can be shared by many people. A library has different sections for different types of books, keeping the information it stores in an organized manner. A library also has a system to track who checks out book, ensuring that it tracks version controls of its stock of information.

Some libraries are public, like a local Public Library, whereas other libraries may be private, like a school's library, which is reserved only for students and faculty.

A code repository is the home for source code and it's relevant resources, allowing collaboration between developers.

A non-relational database, also known as a NoSQL database, is a type of database that does not use the traditional table-based structure found in relational databases. Instead, it uses various data models like key-value, document, column-family, and graph to store and manage data.

Imagine a library that doesn't organize books by the Dewey Decimal System or any other traditional method. Instead, it groups books based on their content, author, or other unique characteristics. This unconventional organization method allows for more flexibility and efficiency when searching for specific information.

A non-relational database is a flexible and efficient way of storing and managing data without using the traditional table-based structure.

A product roadmap is a strategic plan that outlines the vision, direction, and development timeline of a product. It includes key milestones, features, and goals that the product team aims to achieve over time.

Imagine you're planning a cross-country road trip. A product roadmap is like your travel itinerary, outlining the major stops and attractions you want to visit along the way. It helps you prioritize and plan your journey, ensuring you reach your destination in the most efficient and enjoyable way possible.

A product roadmap is a strategic plan that guides the development and growth of a product, similar to a travel itinerary for a road trip.

Product Roadmap

A pull request (PR)is a way for developers to collaborate and propose changes in the codebase, doing so through the approval of another developer. This ensures that all changes are carefully reviewed and tested before being integrated into the codebase. You can think of a pull request as a peer review.

A pull request is like a chef preparing a meal and having their sous chef taste it before being served.

A chef will prepare ingredients and begin to cook a meal, starting with the basic foundation and slowly putting the entire meal together itself. The chef may first start off with working on the sauce. As they prepare the sauce, they will personally taste it as they make it to ensure they are on the right track. Once they think its in a good spot, they will then ask a sous chef or colleague to taste it, to ensure they get a second opinion before sending it out for a customer to eat.

If the sous chef has feedback, the chef will then be able to incorporate that feedback into their preparations, making alterations to the recipe to enhance the quality of the sauce. Once it is back to a place where the chef is confident with it, they will have the sous chef taste it again. When the sous chef gives the thumbs up, they will then use it as the final product for the meal.

A pull request is a way for developers to collaborate on a codebase, ensuring that they review each other's work to only integrate code that is of quality and mutually agreed upon. Common 

 like GitHub, GitLab, and Bitbucket leverage pull requests.

ransfer) API, or RESTful API, is an application programming interface (API or Web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services.

A REST API is the way your waiter writes down your order.

A waiter can record your order in many different ways. Maybe the try to memorize all of the orders and don't write anything down. Maybe they have a blank pad of paper, or pre-organized pad of all menu items. Maybe, they just use an iPad.

Depending on the restaurant and the responsibilities of the waiter, they may choose a specific way to take your order to most effectively facilitate the transfer of information.

A REST API is a style of API that dictates how you can access and use data.

REST API

React is a popular open-source JavaScript library used to build user interfaces, particularly for single-page applications. It allows developers to create reusable UI components and manage the state of their applications efficiently.

Imagine you're building a house, and you have a set of pre-built rooms (kitchen, living room, bedroom) that you can easily assemble together. React is like those pre-built rooms, providing developers with pre-built UI components that can be quickly assembled to create a complete application.

React simplifies the process of building web applications by providing reusable building blocks (components) and efficient state management.

React

React Native is an open-source framework developed by Facebook for building mobile applications using JavaScript and React. It allows developers to create native apps for Android and iOS platforms with a single codebase, leading to reduced development time and effort.

Imagine you're a chef who needs to cook the same dish for two different restaurants, but each restaurant has its own unique kitchen setup and equipment. React Native is like a recipe that helps you create the same dish in both kitchens, using the same ingredients and instructions, while still fitting each kitchen's unique requirements.

React Native allows developers to create mobile applications for Android and iOS platforms using a single codebase, making the development process more efficient and streamlined.

React Native

Refactoring is the process of restructuring and optimizing existing computer code without changing its external behavior or functionality.

Imagine you have a messy room, and you decide to clean and organize it. You might rearrange the furniture, put things in their proper places, and throw away unnecessary items. After the cleanup, the room still serves the same purpose, but it's now more efficient and easier to navigate. Refactoring code is similar to cleaning up a messy room — you're making the code more organized and efficient without changing its purpose.

Refactoring is the process of improving the structure and efficiency of code without altering its functionality.

A relational database is a type of database that stores and organizes data in tables with rows and columns, allowing users to efficiently access, update, and manage related data through established relationships between these tables.

Imagine a library with multiple shelves, each shelf containing a binder. Each binder represents a table, and inside the binders, there are pages with rows and columns. The rows represent individual records, while the columns represent the attributes of those records. Just like how you can easily find information in a library by knowing the location of the binder and the page, you can quickly access data in a relational database by knowing the table and the relationships between different tables.

A relational database is like a well-organized library of data stored in tables, with relationships between tables making it easy to find and manage information.
