How to Dynamically Render Components in React with Correct Case Conversion?

Dynamic Component Rendering in React / JSX

React developers often encounter the need to dynamically render components based on their type. However, using the type "Component" syntax often results in unexpected output, as it compiles to instead of .

To address this issue, the React community has proposed various solutions. One method involves creating separate new methods for each component, providing a convenient way to create instances and ensuring correct case conversion.

However, a more elegant solution exists by leveraging ECMAScript 6 (ES6) syntax. React compiles JSX to JavaScript using the React.createElement method, which expects a string (HTML tag) or a function (React class) as its first parameter. Therefore, by storing the component class in a variable with an uppercase first letter, React automatically recognizes it as a component name.

const MyComponent = Components[type + "Component"];
return <MyComponent />;

This code compiles to:

const MyComponent = Components[type + "Component"];
return React.createElement(MyComponent, {});

This technique allows for dynamic component rendering with correct case conversion, providing a convenient and maintainable solution.
