Question

Accepted Answer

Controlled components are controlled by React, while uncontrolled components are controlled by the DOM.

Controlled components are controlled by React state, while uncontrolled components are controlled by the DOM directly.
Example: Input fields in a form controlled by React state vs input fields with native DOM handling.
Lifecycle methods are methods that are automatically called at specific points in a component's life cycle.
Example: componentDidMount() is called after the component has been rendered to the DOM.
Templates strings allow for embedded expressions and multi-line strings in JavaScript.
Example: `Hello, ${name}!` allows for dynamic content in a string.
Hosting refers to where a website or application is stored and made accessible on the internet.
Example: Hosting a website on a server using services like AWS or Heroku.
Error handling is the process of managing and responding to errors that occur during the execution of a program.
Example: Using try-catch blocks to handle exceptions in JavaScript.
Unit tests are tests that validate individual units or components of a software application.
Example: Writing tests for specific functions or modules to ensure they work as expected.
