When it comes to coding conventions and best practices, casing plays an important role in maintaining consistency and readability. In React, it is recommended to use PascalCase for naming your components. This convention helps distinguish React components from regular HTML elements and improves code clarity.
Using PascalCase for React components means starting the component name with an uppercase letter and capitalizing the first letter of each subsequent word. For example, a component named “MyComponent” follows PascalCase.
On the other hand, HTML elements should be written in lowercase. This convention is followed to differentiate between React components and standard HTML tags. For example, the HTML tag for a paragraph is written as <p> and not <P>.
Here’s an example to illustrate the difference:
// React component
function MyComponent() {
return <div>Hello World!</div>;
}
// HTML element
<p>This is a paragraph.</p>
