When it comes to , the devil is often in the details. Even seemingly simple functions can contain a world of complexity, especially when we aim to make our code , , , and adaptable to varying browser capabilities. JavaScript robust reusable readable Take, for instance, a function that copies text to the clipboard. It might seem straightforward, but there are multiple aspects to consider: What if the is not supported? How can we handle different types of input? Clipboard API Enter Artificial Intelligence To address these questions, I embarked on a journey to craft a function that could stand the test of real-world applications. I had an AI partner on this journey: . copyTextToClipboard GPT-4 So why choose this particular function? While I haven't encountered issues with existing Copy To Clipboard functions, the goal was to create one that not only functions effectively but is also built according to the latest JS standards and best practices. Here's what we developed ( : to open the below code on ) Note Click here CodePen.io /**
 * Copies the provided text to the clipboard.
 *
 * @param {string} text - The text to be copied to the clipboard.
 * @returns {Promise} A promise that resolves when the text has been successfully copied, or rejects when an error occurs or the Clipboard API is not supported.
 */
const copyTextToClipboard = (text) => {
  return new Promise((resolve, reject) => {
    // Check if the text is a string and not empty.
    if (typeof text !== "string" || text.trim() === "") {
      reject(new Error("Invalid text: Text should be a non-empty string."));
      return;
    }

    // Check if the Clipboard API is supported.
    if (!navigator.clipboard) {
      reject(new Error("Clipboard API not supported"));
      return;
    }

    // Try to write the text to the clipboard.
    navigator.clipboard
      .writeText(text)
      .then(resolve) // If successful, resolve the promise.
      .catch(reject); // If an error occurs, reject the promise with the error.
  });
}; So, why should you consider using this function over others? Here are some key reasons: This function checks if the is supported and ensures that the text to be copied is a non-empty string. This makes it more robust against potential misuse. Robust Error Handling: Clipboard API The function leverages for asynchronous execution, making it compatible with syntax and suitable for applications that need non-blocking operations. Asynchronous Operation: JavaScript Promises async/await The function is designed with modern JavaScript best practices in mind, from the use of for function declaration, , to . Code Best Practices: const arrow functions template strings Learn To Prep AI Before Asking Questions Working with GPT on this was quite an experience. I learned the hard way that it's essential to and provide as much as possible-the more precise and specific the instructions, the more satisfactory and applicable the results. define GPT's persona context Here's an example of what I asked GPT: Act as a JavaScript Developer using the latest stable ECMA Script standards that are supported on modern browsers. You only write robust, reusable, readable, well-documented, performant, and secure code that conforms to best practices for production environments. Perform a code review of the following JavaScript function and if it fails your standards and practices, rewrite it with explanations of what you changed and why: that I felt was quite good. I then pasted a version of copyTextToClipboard In response, GPT not only followed my instructions but also added additional value, enhancing readability, reusability, and error handling in the function. The collaboration resulted in a piece of code I was happy to add to my project. Considerations It's important to understand the caveats when working with a function like this: The Clipboard API requires and only works in a secure context (HTTPS), which could limit the usability of your function in some situations. The use of the Clipboard API: permission Although the Clipboard API is widely supported, there may be with older browsers or less popular ones that do not fully support this API. Browser Compatibility: compatibility issues While this function is unlikely to be a performance bottleneck, one has to keep in mind that varied results could occur depending on the to be copied. Performance: size of the text Closing As we continue to adopt AI tools like and in our coding journeys, we not only enhance our coding practices but also create new opportunities for innovation and improvement. GPT Google Bard Feel free to use this function in your projects and, more importantly, reference for the latest version. this function on CodePen.io Till next time - John 🙂
