So, what is a higher-order component? A higher-order component is essentially a function that takes an existing component and returns a new component with added functionality. Think of it as a wrapper that enhances your components without modifying the original. The main idea here is reusability. Instead of copying the same logic into multiple components, you can wrap them with a higher-order component and share that logic seamlessly. In simple terms, you can imagine it like this.
