For a more modern focus, the "JavaScript ES6+ Modern Features Guide" by Dargslan is a focused, practical guide to mastering the syntax and patterns of modern JS.

async function loadProducts() try const response = await fetch('https://api.example.com/products'); if (!response.ok) throw new Error('Network error'); const products = await response.json(); renderProducts(products); catch (error) console.error('Failed to load:', error);
