7We can use import() syntax to easily and cleanly load it conditionally:
8// other-file.js
9
10if (somethingIsTrue) {
11  import('./something.js').then((module) => {
12    // Use the module the way you want, as:
13    module.hi('Erick') // Named export
14    module.bye('Erick') // Named export
15    module.default() // Default export
16  })
17}
