### Rezi UI Animation Script

Source: https://www.rezi.ai/job-search

JavaScript code snippet that uses GSAP and SplitType libraries to animate text elements on the page based on scroll position and viewport width. It dynamically adjusts animation start and end points for mobile devices.

```javascript
document.addEventListener('DOMContentLoaded', function() {
  // Function to check if the viewport width is 767px or less
  function isMobile() {
    return window.innerWidth <= 767;
  }

  // Split text into individual words
  const layoutText = new SplitType(".layout484_text", { types: "words" });
  const layoutTL = gsap.timeline();

  // Define different start and end values for mobile devices
  let startValue = isMobile() ? "top 35%" : "top center";
  let endValue = isMobile() ? "bottom 90%" : "bottom center";

  layoutTL.from(layoutText.words,{
    // Initial opacity for each word
    opacity: 0.25,
    // Stagger animation of each word
    stagger: 0.1,
    scrollTrigger: {
      trigger: ".section_layout484",
      // Trigger animation when .section_layout484 reaches certain part of the viewport
      start: startValue,
      // End animation when .section_layout484 reaches certain part of the viewport
      end: endValue,
      // Smooth transition based on scroll position
      scrub: 2
    }
  });
});
```

### Initialize Drag-and-Drop File Upload

Source: https://www.rezi.ai/ai-resume-builder

Sets up a drag-and-drop interface for file uploads. It attaches event listeners to a specified drop zone for drag events and file drops, and also enables file selection via a hidden file input triggered by clicks on the drop zone.

```javascript
let fileInput;
const initializeDragDrop = () => {
  const dropZone = document.getElementById('data-resume-dropzone');
  if (!dropZone) {
    console.warn('No drag drop zone found. Add data-resume-dropzone attribute to your drop zone element.');
    return;
  }

  fileInput = document.createElement('input');
  fileInput.type = 'file';
  fileInput.accept = '.pdf,.docx';
  fileInput.style.display = 'none';
  fileInput.addEventListener('change', (event) => {
    const file = event.target.files[0];
    if (file) {
      handleResumeUpload(file); // Assuming handleResumeUpload is defined elsewhere
    }
  });
  document.body.appendChild(fileInput);

  // Prevent default drag behaviors
  ['dragenter', 'dragover', 'dragleave', 'drop'].forEach(eventName => {
    dropZone.addEventListener(eventName, preventDefaults, false);
    document.body.addEventListener(eventName, preventDefaults, false);
  });

  // Highlight drop zone when item is dragged over it
  ['dragenter', 'dragover'].forEach(eventName => {
    dropZone.addEventListener(eventName, highlight, false);
  });

  ['dragleave', 'drop'].forEach(eventName => {
    dropZone.addEventListener(eventName, unhighlight, false);
  });

  // Handle dropped files
  dropZone.addEventListener('drop', handleDrop, false);

  // Handle click to select file
  dropZone.addEventListener('click', () => {
    if (fileInput) {
      fileInput.click();
    }
  });

  function preventDefaults(e) {
    e.preventDefault();
    e.stopPropagation();
  }

  function highlight() {
    dropZone.classList.add('dragover');
  }

  function unhighlight() {
    dropZone.classList.remove('dragover');
  }

  function handleDrop(e) {
    const dt = e.dataTransfer;
    const files = dt.files;
    if (files.length > 0) {
      handleResumeUpload(files[0]); // Assuming handleResumeUpload is defined elsewhere
    }
  }
};

// Initialize when DOM is loaded
if (document.readyState === 'loading') {
  document.addEventListener('DOMContentLoaded', initializeDragDrop);
} else {
  initializeDragDrop();
}
```

### Drag-and-Drop File Upload Initialization

Source: https://www.rezi.ai/keyword-scanner

Sets up the drag-and-drop interface for a specified drop zone element. It prevents default browser behaviors for drag events, adds visual feedback classes ('dragover') during dragging, handles dropped files, and provides a click-to-upload fallback mechanism.

```javascript
let fileInput;
const initializeDragDrop = () => {
    const dropZone = document.getElementById('data-resume-dropzone');
    if (!dropZone) {
        console.warn('No drag drop zone found. Add data-resume-dropzone attribute to your drop zone element.');
        return;
    }
    fileInput = document.createElement('input');
    fileInput.type = 'file';
    fileInput.accept = '.pdf,.docx';
    fileInput.style.display = 'none';
    fileInput.addEventListener('change', (event) => {
        const file = event.target.files[0];
        if (file) {
            handleResumeUpload(file);
        }
    });
    document.body.appendChild(fileInput);

    // Prevent default drag behaviors
    ['dragenter', 'dragover', 'dragleave', 'drop'].forEach(eventName => {
        dropZone.addEventListener(eventName, preventDefaults, false);
        document.body.addEventListener(eventName, preventDefaults, false);
    });

    // Highlight drop zone when item is dragged over it
    ['dragenter', 'dragover'].forEach(eventName => {
        dropZone.addEventListener(eventName, highlight, false);
    });

    ['dragleave', 'drop'].forEach(eventName => {
        dropZone.addEventListener(eventName, unhighlight, false);
    });

    // Handle dropped files
    dropZone.addEventListener('drop', handleDrop, false);

    // Handle click to select file
    dropZone.addEventListener('click', () => {
        if (fileInput) {
            fileInput.click();
        }
    });

    function preventDefaults(e) {
        e.preventDefault();
        e.stopPropagation();
    }

    function highlight() {
        dropZone.classList.add('dragover');
    }

    function unhighlight() {
        dropZone.classList.remove('dragover');
