The Ultimate ReactJS Developer Course

The introduction to the ultimate reactjs developer course explains how the react tool chain and JSX require transpilation with Babel to run in older browsers while leveraging modern features.

Explore webpack and babel to transpile and bundle JavaScript, adopt module scope with exports, and optimize the React tool chain for development and production deployments.

Learn to manage dependencies with node and npm, create a package.json, install React, and use scripts to bundle and build for development or production.

Discover how to convert ES6 to ES5 with Babel, using ES2015 and React presets, by installing, configuring, and building a project for iOS 5 compatibility.

Discover how to configure webpack to bundle a React app into one optimized bundle.js, converting imports to commonjs, using babel loader, and setting entry and output for development and production.

Learn how to use Webpack dev server for live reloading and in-memory bundling, enable source maps, and switch to production builds with minimization and plugins.

Learn to bootstrap a React app with Create React App, install via npm or yarn, and explore the built-in structure and dev server commands like start, build, and eject.

Explore the create-react-app workflow from the index.js entry to production builds, covering service workers, CSS, source maps, webpack dev server, and the eject option for config, plus npm test basics.

Explore functional programming in JavaScript, focusing on immutability and map versus forEach. See how map returns a new array and how React favors immutable patterns.

Explore functional programming with map, filter, and reduce in JavaScript, learn how to transform arrays into React components, and apply predicates to filter data for clean, modern React code.

Understand the execution context and this in JavaScript, explore constructor functions and the new keyword, prototype inheritance, and how passing methods can make this undefined in strict mode.

Explore execution context and this binding in JavaScript, and use call, apply, and bind to control this for reliable method calls in React component hierarchies.

Explore ES6 features like template strings with backticks for clean inline variable interpolation and default function parameters that gracefully handle missing arguments, improving JavaScript and React code clarity.

Explore es6 rest and spread operators, turning the arguments object into arrays and spreading arrays into calls, with patterns for named and arbitrary arguments in React.

Discover ES6 arrow functions, replacing the function keyword with concise syntax, learn parameter rules for zero or one arguments, and see how arrow functions fix this binding via lexical scope.

Explore ES6 destructuring to pull values from arrays and objects, swap variables, skip values, and handle nested structures for concise, readable assignments.

Master ES6 modules and classes in React by using import and export (default and named), and explore prototype-based behavior and class inheritance with extends and super.

Demonstrate ES6 promises for asynchronous JavaScript, comparing callbacks and the event loop, and show how promises with node fs reduce the pyramid of doom and boost readability.

Explore how to create and consume ES6 promises, chain then calls, and handle errors with catch while reading files, returning promises for clean async workflows.

Explore how es6 fetch and isomorphic-fetch enable lightweight ajax without heavy libraries, and learn generators, yield, and their use in powering async patterns in javascript.

Explore how generators and promises approximate async/await for ajax-driven RESTful data in a user and repo flow, then compare with real async/await in node and react.

Explore building a basic React app with boilerplate code, JSX syntax, and the roles of React and ReactDOM in rendering to the DOM, while setting up with npm install.

Use the render function to mount a React app into a div with an id. Understand why rendering into body is discouraged and prefer a dedicated mount point.

Explore how JSX translates to React.createElement and why wrapping elements matters. Learn to manage component state with getInitialState, render dynamic profiles, and render state expressions in JSX.

Build a React app with ES6 class components, using constructor and super(props) to initialize state. Create a reusable profile component, pass props, and render dynamic profiles and hobbies with map.

Show how a child component triggers a parent state change to add a user, using on click, binding, set state with immutability, and passing the function down as a prop.

Learn how to manage state with parent components, modularize a React app into separate components, and use export/import patterns to bind handlers and pass props for scalable app state.

Learn to implement React controlled inputs for name, bio, and hobby, manage state with onChange and setState, and submit a new user to the profile list.

Discover how to build functional stateless components in React by using arrow functions, omitting return for single expressions, and passing props as the sole argument, enabling concise, debuggable components.

Learn how to fetch profiles from a server with fetch, place data fetching in the component did mount, handle CORS issues, and refactor into a getProfiles API utility with promises.

Explore React component lifecycle methods, including component will mount and component did mount, state-driven renders, props and children, and cleanup with intervals and unmounting.

Learn to reuse cross-cutting behavior with higher-order components, wrapping components to share state and lifecycle logic, while using prop types and default props for robust interfaces.

Explore how React uses keys to optimize reconciliation and prevent unnecessary re-renders, and learn how to implement shouldComponentUpdate for selective rendering in large apps.

Explore styling React apps with inline styles and traditional CSS style sheets, evaluating local scope, reusability, and the limits of inline styles for hover states and other CSS features.

Explore how CSS modules create local scope by importing styles as a module and using styles.x for component-specific classes, preventing global cascade.
