🥚Dynamic Imports

Dynamic imports allow you to import and execute a module or a script on demand at runtime. This can be useful when you want to load a module or a script only when it is needed, instead of loading it upfront with the rest of your code.

Dynamic imports are written using the import keyword followed by a module or script path in parentheses, and they return a promise that is resolved with the module or script exports. Here's an example of how you can use a dynamic import to load a module on demand:

async function loadModule() {
  const module = await import('./module.js');
  // Use the module
}

In the example above, the loadModule function uses a dynamic import to load the module.js module. The execution of the function is paused until the promise returned by the dynamic import is resolved, and the resolved value is stored in the module variable.

Dynamic imports can also be used to load scripts on demand. Here's an example of how you can use a dynamic import to load a script:

async function loadScript() {
  const script = await import('./script.js');
  // The script has been executed
}

In the example above, the loadScript function uses a dynamic import to load the script.js script. The execution of the function is paused until the promise returned by the dynamic import is resolved, and the resolved value is stored in the script variable. The script will be executed when it is loaded.

Dynamic imports can be useful when you want to optimize the loading time of your application by only loading resources when they are needed. They can also be used to implement features like code splitting, which allows you to split your code into smaller bundles that can be loaded on demand.
