DOM

jQuery

Replacing jQuery $('.class')

Vanilla JavaScript

const $ = (selector) => {
  const elements = document.querySelectorAll(selector);
  return {
    hide: () => elements.forEach(el => el.style.display = 'none'),
    show: () => elements.forEach(el => el.style.display = ''),
    text: (str) => elements.forEach(el => el.textContent = str),
    elements
  };
};

// Usage:
// $('.nav-link').hide();

Why Use This?

jQuery was essential when browsers had completely different DOM APIs and bugs. Today, `document.querySelectorAll` provides a standard and equally succinct selector API natively. You don't need a heavy DOM abstraction library to manipulate the page.
