Dynamic imports (import()) can be used not only with React.lazy for lazy loading components. They are useful in any cases where you need to defer loading a module until it is actually used, to reduce the initial bundle size and speed up page loading.

Examples of using dynamic imports outside React.lazy:

  • Loading utilities or libraries only when needed (for example, a date handling library if the user opens the relevant section).
  • Importing configurations or data that depend on runtime conditions.
  • Implementing plugins or modules that are loaded dynamically depending on user actions.

Example:

button.addEventListener('click', async () => {
  const { formatDate } = await import('./dateUtils.js');
  console.log(formatDate(new Date()));
});

Thus, dynamic imports allow optimizing loading and improving application performance.
