• Implement an Error Boundary component to intercept errors in child components

Learning Objective

Learn to build form elements that are controlled by React. Learn to fetch form data directly from the DOM. Implement debouncing & other techniques to efficiently handle multiple form elements.

Topics

• Controlled Form Components
• Uncontrolled Form Components
• Handling inputs efficiently
• Project - Building a currency converter

Hands-on

• Turn an input element into a controlled component

Learning Objective

Implement shared logic using render props. Learn to reuse component logic using the HOC pattern.

Topics

• Render Props
• Higher Order Components

Hands-on

• Create a Currency-Converter component that implements render props to provide the result which is then rendered on the screen 
• Build a higher order function that empowers our App component with tools to fetch currency rates after conversion

Learning Objective

Learn to render children in a DOM node that is outside of the parent's DOM hierarchy. Understand how event bubbling works with Portals.

Topics

• Introduction to Portals
• Event bubbling in Portals

Hands-on

Work with Portals to render a dialog box component in a DOM element other than the root div where the React app is mounted

Learning Objective

Understand the nuances of data flow in a React application, and the issues with sharing global data using props in a deeply nested application. Learn and understand all about the Context API that lets you share global data without using props. 

Topics

• Unidirectional Data Flow
• Challenges with Props
• The Context API

Hands-on

Instantiate a context, and provider and consumer components to trickle data down to the component hierarchy

Learning Objective

Get an introduction to the Hooks API and the motivation behind them. Learn to incorporate stateful properties in a function component using the useState() hook.Learn to ingest data from a Context provider using hooks and to implement the useReducer() hook. Finally, learn to write your own hook. 

Topics

• Understanding Hooks 
• The useState hook 
• Side effects using the useEffect hook 
• The useContext hook 
• The useReducer hook 
• Writing your own hook 

Hands-on

• Build a PowerTags component that can be used to dynamically add/remove tags or keywords
• Use the useEffect function to fetch data from a stock app
• Implement the useContext hook to consume data from a context provider
• Use the useReducer hook to offload state management and define actions and their resulting state changes
• Build a custom hook named ‘useGeoLocation’ which accesses the HTML5 GeoLocation API to continually fetch the latitude and longitude of the user’s location

Learning Objective
