Question

What are the use cases for dynamic imports?

Answer 1

Below are some of the use cases of using dynamic imports over static imports,

1. Import a module on-demand or conditionally. For example, if you want to load a polyfill on legacy browser

if (isLegacyBrowser()) {
    import(···)
    .then(···);
}

1. Compute the module specifier at runtime. For example, you can use it for internationalization.

import(`messages_${getLocale()}.js`).then(···);

1. Import a module from within a regular script instead a module.
