How to Dynamically Import ES6 Modules in JavaScript?

Dynamic ES6 Module Imports Unraveled

If you're seeking to import ES6 modules dynamically, you might have encountered the limitation where "import" and "export" declarations can only reside at the file's top level. To address this, let's explore the solutions.

Initially, System.import was a promising option, but its present status remains unclear. Fortunately, ECMAScript 2020 introduced dynamic imports, now available via the babel-preset.

For conditional module imports, here's a use case:

if (condition) {
    import('something')
    .then((something) => {
       console.log(something.something);
    });
}

This approach returns a promise, with its resolution containing the imported module. The dynamic import proposal offers additional features such as multiple dynamic imports, default imports, and JavaScript file imports. Explore dynamic imports further here.
