Look Up Any HTTP Response Status Code HTTP Status Code Reference tool for network operations.

Under the hood, it utilizes a combination of client-side JavaScript and browser APIs to provide an efficient and private experience. The tool's core data structure is an array of objects, where each object represents an HTTP status code and contains properties such as `code`, `text`, and `desc`. This array is then filtered using the `filter` method based on user input, which can include searching by numeric code, reason phrase, or description. The search functionality is case-insensitive and uses the `trim` and `toLowerCase` methods to normalize user input.

The tool also employs React hooks, specifically `useState` and `useMemo`, to manage state and optimize performance. For example, the `filtered` array is computed using `useMemo`, which ensures that it only re-computes when the dependencies change, reducing unnecessary re-renders. Additionally, the `handleCopy` function uses the `navigator.clipboard` API to copy status codes to the user's clipboard, providing a seamless and intuitive experience.

In terms of rendering, the tool uses JSX and React components to generate the user interface. The `InputWithHelp` component is used for search input, while the results are rendered as a list of buttons, each containing a code badge, text content, and copy indicator. The `getClassName` function is used to determine the class name for each status code based on its value, and the `getStatusColor` function returns a CSS class string that defines the color scheme for each code.

The tool's mobile-first responsive design ensures that it adapts to different screen sizes and devices, providing an optimal experience regardless of the user's device. By leveraging modern JavaScript features such as ES6+ syntax and React hooks, the tool achieves a high level of performance, security, and maintainability. Furthermore, it adheres to web standards and RFCs, ensuring that it is compatible with a wide range of browsers and devices.
