Incremental DOM vs. Virtual DOM - Memory Usage

Compare memory usage between Incremental DOM and Virtual DOM by creating a large list of elements and profiling the memory footprint.

/* Incremental DOM example */
const IncDom = IncrementalDOM; // Assuming IncrementalDOM library is loaded
let listContainer = document.createElement('div');

function renderListWithIncDom(items) {
  IncDom.patch(listContainer, () => {
    items.forEach(item => {
      IncDom.elementOpen('div', item.key);
      IncDom.text(item.text);
      IncDom.elementClose('div');
    });
  });
}

// Generate a large list
let largeList = Array.from({ length: 10000 }, (_, i) => ({ key: `item-${i}`, text: `Item ${i}` }));
// Render using Incremental DOM
renderListWithIncDom(largeList);
console.log('Incremental DOM Memory usage:', window.performance.memory.usedJSHeapSize);

This piece of code creates a large list of divs using Incremental DOM. It then logs the memory usage after rendering. Include the IncrementalDOM library before running this code.

/* Virtual DOM example using React */
const { createElement } = React;
const { render } = ReactDOM;

function renderListWithVirtualDom(items) {
  return items.map(item => createElement('div', { key: item.key }, item.text));
}

let largeListVDOM = Array.from({ length: 10000 }, (_, i) => ({ key: `item-${i}`, text: `Item ${i}` }));
let listElementsVDOM = renderListWithVirtualDom(largeListVDOM);
let virtualDomContainer = document.createElement('div');
document.body.appendChild(virtualDomContainer);
render(createElement('div', null, ...listElementsVDOM), virtualDomContainer);
console.log('Virtual DOM Memory usage:', window.performance.memory.usedJSHeapSize);

This piece of code creates a large list of divs using React's Virtual DOM and renders it to the DOM. It then logs the memory usage post-render. Include React and ReactDOM JavaScript libraries before running this code.
