Summary Notes

Introduction to React

  • React is a JavaScript framework designed to simplify the process of writing JavaScript code.
  • It is widely used and favored by developers for its ease of use and component-based structure.
  • React's component-based architecture allows for separation of concerns, making each part of an application independent.

"In essence, React is a JavaScript framework... and a framework just makes writing a language easier."

  • This quote explains that React is a tool that simplifies JavaScript coding.

"What's special about React is that it is component-based."

  • This quote highlights the core feature of React: its component-based nature, which differentiates it from traditional JavaScript coding.

Understanding Component-Based Architecture

  • In traditional JavaScript applications, interactions can affect the entire application due to the linked nature of the DOM.
  • React, however, treats each part of the application as an independent piece, similar to puzzle pieces.
  • This independence reduces the impact of interactions within one component on the rest of the application.

"In a regular JavaScript application everything here will be linked to each other... the entire app will be impacted by me pressing this button because in JavaScript everything is linked together in the DOM."

  • The quote describes the interconnected nature of traditional JavaScript apps and how actions can affect the entire DOM.

"Each aspect of this application is its own piece... this record button over here is different to the the snav bar."

  • This quote illustrates the concept of components in React, where different elements like buttons and navigation bars are separate entities.

Practical Example of React's Components

  • The speaker provides an example of navigating to a "road map" page in a React application.
  • In traditional JavaScript, the entire application would refresh upon navigation.
  • With React, only the specific component that needs to change (e.g., the road map page) will refresh, while the rest of the application (e.g., the navigation bar) remains unaffected.

"In a regular Javascript app everything in the entire app will refresh... however in react because it's one part of the application... only the road map page will refresh and show and the nav bar will stay the same."

  • This quote demonstrates the advantage of React's component-based structure in minimizing unnecessary refreshes and maintaining the state of other components.

Setting Up a React Application

  • React applications can be easily set up using the command line with a package manager.
  • The speaker uses Visual Studio Code (VS Code) as the development environment.
  • The process involves creating a new React application using the npx create-react-app command and naming the application.

"To run react all we need to do is go into our vs code folder... and run npx create-react-app and we can actually just call this let's say YouTube."

  • This quote provides a step-by-step instruction on initiating a new React project using the command line in VS Code, emphasizing the simplicity of starting a React application.

Starting a React Application

  • Installation of necessary packages to run a React application has been completed.
  • To initiate the React app, one must navigate to the project directory and execute npm start.
  • The command launches the React application, displaying the default boilerplate code.

"So everything has been installed and to go into this we just need to do CD YouTube and Run npm start this basically starts the react application and we can see here the boilerplate code for our react app."

This quote explains the process of starting a React application after installation by changing the directory to the project folder and running npm start, which reveals the boilerplate code of the app.

  • The app.js file can be edited to change what is displayed on the page.

"And if we go to say app.js we can see edit and then SRC app as you can see here on the page so we can just write whatever here let's say it's YouTube as you can see here YouTube."

The quote highlights that by editing the app.js file, one can modify the content displayed on the webpage, using the example of changing text to "YouTube".

Simplifying the React Application

  • Simplification can be done by deleting unnecessary code and starting with a simple output like "hello."

"Let's actually delete everything so we can kind of simplify stuff just write. hello."

This quote suggests that to simplify the React application for educational purposes, one can strip away the existing code and start with something basic, such as outputting the word "hello".

  • The concept of running code to display it on a page rather than just having a folder might be confusing for beginners.

"So this may be a little bit confusing to you because you know we just ran something to display code rather than just having a folder so that's maybe a bit confusing to you."

The quote acknowledges that for those new to React, the idea of running code to display it, as opposed to simply having static files in a folder, may be initially perplexing.

React Functionalities and Component Creation

  • React allows for the creation of components, such as a navigation bar, which can be reused across the application.

"Right let's say we wanted to create a nav bar in a regular like let's say HTML or JavaScript page we would just write something like nav and have a nav bar here."

The quote discusses how one would typically create a navigation bar in plain HTML or JavaScript, setting the stage for a comparison with React's approach.

  • In React, components are created as functions in separate files and imported into the main application file.

"But there's no point to that cuz we're using react so instead what we can do is that we can make a new file called navbar doj make the function which is from JavaScript so function navbar and then open that up return div Navar."

This quote introduces the React methodology of creating a new file for a component, defining it as a JavaScript function, and returning the desired HTML within that function.

  • Components must be properly exported from their file and imported into the application file where they are used.

"Oh oopsie we have to. we have to actually export the nav bar so actually my fault there so if we do this again we imported navbar."

The quote illustrates the common mistake of forgetting to export a component, which is necessary for it to be used in other parts of the application.

React Component Reusability and Management

  • React's component structure allows for a single source of truth for each part of the application, facilitating easier updates and management.

"Not everything will be in one page that's the main idea for bigger applications we want different aspects and let's say we want a Navar in every page we can just create a Navar boilerplate code where we can just have our Navar and display it throughout our whole application rather than redoing it in each page."

This quote explains the advantage of React's component-based architecture, where a component like a navigation bar is created once and can be included on multiple pages, avoiding repetition and easing maintenance.

  • Updating a component in React is straightforward as it involves making changes in a single location rather than across multiple files.

"And on top of that it just makes everything easier to manage so let's say we want to update the Navar we don't have to scroll through hundreds of lines of code we can just go over here and update the nav bar really easily."

The quote emphasizes the ease of managing and updating components in React, as changes need to be made in only one place, saving time and reducing complexity.

Learning React

  • The speaker begins to share personal experiences and methods used to learn and master React.

"Okay Nazar um now that we know what react is and you probably know what react is and we've covered the basics how do we learn react there are three things that I did to learn and master react."
