The provided code does not have any immediate irregularities or issues that need correction. However, there are a few optimizations you might consider:

1. Debounce Copy Click: The copyClick function in the script should be debounced to prevent excessive clipboard operations during rapid clicks.

import debounce from 'lodash/debounce';

const handleCopyClick = debounce((text: string) => {
  copy(text);
}, 300);

const bindEventListeners = () => {
  document.querySelectorAll('.copy-button').forEach(button => {
    button.addEventListener('click', (e) => {
      e.preventDefault();
      const targetElement = e.target;
      let text;

      if (targetElement.tagName === 'SPAN') {
        text = targetElement.textContent || '';
      }

      if (!text || typeof text !== "string") return;

      handleCopyClick(text);
    });
  });
};

onMounted(bindEventListeners);

This will limit how often the clipboard operation is triggered when multiple clicks occur quickly.

2. Remove Unnecessary Import for nextTick:
   Since nextTick is imported but never used within this scope, it can be removed for better readability and performance.

+// import { nextTick } from 'vue';

By making these minor adjustments, the code will perform more efficiently without compromising functionality.
