JavaScript Modules (import/export)

What is the primary benefit of dynamic imports using import()?

// lazy.js
export const heavyOperation = () => {
  // Complex computation
};

// main.js
const loadModule = async () => {
  const module = await import('./lazy.js');
  module.heavyOperation();
};

They make the code execute faster
They allow importing without using module syntax
They enable loading modules conditionally and on-demand
Dynamic imports using import() provide several key benefits, primarily enabling conditional and on-demand module loading: 1) They allow modules to be loaded asynchronously when needed, improving initial load performance, 2) They support conditional loading based on runtime conditions or user actions, 3) They return a Promise, making them suitable for modern async/await patterns, 4) They enable code-splitting in bundlers like webpack, reducing initial bundle size, 5) They're useful for implementing lazy loading in applications, loading features only when required, 6) They help in implementing progressive enhancement and fallback functionality, 7) They support dynamic module specifiers, allowing module paths to be determined at runtime.
They provide better error handling
