Learn Front-End Basics

Learn Front-End Basics

With React being a front-end library for creating user interfaces, it is essential to learn the basics of the front-end. The front end of web applications is the portion visible to end-users or the part the end-users can interact with. As a React developer, you should be knowledgeable about all the popular front-end technologies. 
 

  • HTML
  • HTML

    HTML stands for HyperText Markup Language. It is a standard, de-facto language for creating the structure of web applications and websites. Hypertext implies text within a text, i.e., the text having a link within it that refers to another text. Meanwhile, a markup language is a computer language for applying layout and formatting conventions to text documents. 
     

  • CSS
  • CSS

    CSS is an acronym for Cascading Style Sheets. It is a style sheet language that describes how the documents scripted in the markup language should appear on the screen. In simple terms, CSS describes the presentation of HTML elements on web pages. It makes web pages more presentable and appealing.  
     

  • CSS frameworks

    Web designing is the process of planning and creating the design of websites or web applications that you see on the internet. In simple terms, it is the process of planning and arranging digital content on web pages so that they reflect an organization’s brands and provide users with an amazing experience.  
     

  • What is node js?
  • What is node js?

    Node.js is an open-source runtime environment for JavaScript. With Node.js, it has become possible for developers to leverage JavaScript to develop the back-end of web applications or websites. It runs on top of the JavaScript engine and runs JavaScript code outside a browser. 
     

  • What is npm?
  • What is npm?

    NPM is an acronym for Node Package Manager. It is a default package manager for Node.js, JavaScript’s runtime environment. It comprises a repository that hosts JavaScript packages and a command-line interface (CLI) for downloading and installing those hosted packages. 
     

React Basics

React Basics

After you understand the basics of the front end and acquire some essential developer skills, you have to move on to learning and mastering the basic concepts of the React library. Start with understanding what React is, how to install and set up, and move forward to learn its components, syntax, state, and other aspects. 
 

  • What is react?
  • What is react?

    React is a front-end library based on JavaScript for creating interactive user interfaces (UIs) based on UI components. It makes creating UIs painless. Developed and maintained by Meta, it is a free and open-source components-based library concerned with only state management and rendering that state to DOM.

    Now, it is time to install and set up React on the system. To do so, you need first to install and configure Node.js. Though there are a lot of ways to set up React, doing it using npm is one of the efficient ones as it assists in accelerating the development process further. 
     

  • What is JSX in react?
  • What is JSX in react?

    JavaScript Syntax Extension is the full form of JSX. It is the React extension to the JavaScript language. It provides a way for developers to structure component rendering through the syntax they are familiar with. JSX is primarily used to build React components. However, many components are also developed using pure JavaScript. 
     

  • React Components
  • React Components

    React components are simply pieces of code that are reusable. They are analogous to JavaScript functions but operate in isolation. There are two types of React components: Class components and Function components. 
     

  • State in react
  • State in react

    A state in React is a built-in object that stores the data or information about a component. Over time, it is possible to change the state of components. Whenever a component’s state changes, the component re-renders. The change in the state of the component takes place in response to user actions or any system-generated event. 
     

  • Props in react
  • Props in react

    Pros in React are simply arguments passed to React components. HTML attributes help in passing the arguments to React components. In other terms, we can refer to props as elements to pass data from one React component to another (from a child component to a parent component(s)). 
     

  • Keys and Map in react
  • Keys and Map in react

    A key is a string attribute that you need to include while you create a list of elements in React. It identifies which elements in the list have changed, removed, and added. 
    In React, a map is a data structure that stores data in the form of key-value pairs. Each data stored in a map is unique, and there are no duplicates. 
     

React Intermediate

React Intermediate

After learning the basics you can scratch the intermediate topics of reacts which includes, different hooks, custom hooks, form handling, etc.

 

  • React Styling
  • React Styling

    In react styling we can use all three types of CSS styling with React, which include, inline, internal, and external.

     

  • React Form Handling
  • React Form Handling

    Form Handling is used to verify and filter the data entered by the user before it is used to send to the server. In React from handling, we use the useState() along with onchange event to handle the form data.

     

  • React Data Handling
  • React Data Handling

    We use the normal JavaScript fetch API to access the data from the server and use the React components to render the data.

  • React Hooks
  • React Hooks

    Hooks were introduced in React 16.8 version, and they allow us to manage the state and use the other features of react, without writing the class.

  • React Custom Hooks
  • React Custom Hooks

    Custom Hooks offer the flexibility of sharing logic that wasn't possible in React components before.

  • Context in React
  • Context in React

    Using the context we can pass the properties along in the React component trees without writing the props manually in every component.

     

React Advance

After you develop an in-depth understanding of the basic concepts of React, go with learning the advanced concepts. 
 

  • Lazy Loading in React
  • Lazy Loading in React

    In React, lazy loading is the concept of loading a component or part of code whenever it is required. It is often referred to as code splitting and data fetching. Alternatively, we can define lazy loading as a technique of rendering only the needed or critical UI items first and, later, rolling the non-critical ones. 
     

  • State Management in React
  • State Management in React

    React applications are the combination of UI components, where each component manages its state internally. This works well for small applications with a few UI components. When it comes to large applications with more components, it becomes complex to manage the state of components. This is where state management is essential for React applications. 
     

  • Portals in React
  • Portals in React

    Portals offer an approach to rendering the child component into a DOM node that is outside the DOM hierarchy of the parent component. Since React’s 16.0 version, portals have been introduced. 
     

  • React Routers
  • React Routers

    In React, React Router is a standard library for routing. It helps you navigate through the views of various components of a React application. In addition, it assists in changing the browser URL and maintaining the UI in synchronization with the URL. 
     

  • Theming in React
