What is the method for displaying an HTML file once a certain condition is met in JavaScript code?

One potential solution to the problem you are facing is to escape the backticks inside the string by using backslashes ("\`") before them. This can be done in the code block where you set the background image by modifying the code to: 

document.body.style.backgroundImage = `url(\`${source}\`)`;
This way, the backticks inside the string will be treated as a part of the URL string and not as the start and end of a JavaScript template literal. Additionally, you should remove the extra semicolon at the end of the line, resulting in: 

document.body.style.backgroundImage = `url(\`${source}\`)`
This should resolve the error you are seeing.

Thank you for sharing the solution! That's a great suggestion.👍 Just to clarify, the backticks inside the string are treated as a part of the URL string and not as the start and end of a JavaScript template literal when you escape them using backslashes ("\`") before them. Also, removing the extra semicolon at the end of the line is important to resolve the error you are seeing. Let me know if you have any other questions or if there's anything else I can help you with.

To display the HTML code when a certain condition becomes true in JavaScript, you can modify your content.js file as follows: 
const landing = `
  <!DOCTYPE html>
  <html>
    <head>
      <title>Random Background</title>
      <style>
        body {
          margin: 0;
          padding: 0;
          background-size: cover;
          background-position: center;
          background-repeat: no-repeat;
          height: 100vh;
        }
        #video-background {
          position: fixed;
          right: 0;
          bottom: 0;
          min-width: 100%;
          min-height: 100%;
          z-index: -1;
        }
      </style>
    </head>
    <body>
      <video id="video-background" autoplay muted loop>
        <source src="" type="video/mp4">
        <source src="" type="video/webm">
      </video>
      <script>
        // Define an array of image sources
        const imageSources = [
          "4.webp",
          "5.jpg"
        ];

        // Define an array of video sources
        const videoSources = [
          "2.mp4",
          "3.mp4"
        ];

        // Select a random image or video source
        const randomIndex = Math.floor(Math.random() * 2); // 0 for image, 1 for video
        const source = randomIndex === 0 ? imageSources[Math.floor(Math.random() * imageSources.length)] : videoSources[Math.floor(Math.random() * videoSources.length)];

        // Set the background using the selected source
        if (randomIndex === 0) {
          document.body.style.backgroundImage = "url(" + source + ")";
        } else {
          const video = document.getElementById('video-background');
          video.querySelector('source[type="video/mp4"]').src = source;
          video.querySelector('source[type="video/webm"]').src = source.replace('.mp4', '.webm');
          video.load();
        }
      </script>
    </body>
  </html>
`;

const lest = ["heru", "firu"];
for (const lul of lest) {
  if (lul === "heru") {
    document.open();
    document.write(landing);
    document.close();
  }
}
In this code, we have removed the landing function and put the HTML code directly into a string variable. Then, we have used document.open() to open a document stream for writing output, document.write() to write the HTML code to the stream, and document.close() to close the stream. We have also modified the if statement to use const lul instead of lul, and to compare it directly to "heru" instead of using the === operator on "heru" and lul. Finally, we have concatenated the source variable inside the if block using the + operator instead of using template literals. This allows us to avoid the error you were seeing. Using this code should display the HTML code when the condition becomes true, and should avoid the error you were encountering.
