### ⭐ Suggestion

I'm curious to hear thoughts on introducing an `importMap` option in `compilerOptions`.

Some initial thoughts:

- Import maps are a WICG standard.
- They can effectively replace `paths` for most use cases.
- They're supported by Deno.
- Projects with colocated Node and Deno workspaces could leverage the same source of truth regarding imports/aliases.
- Import maps provide the ability to configure `scopes` (extremely useful in my experience)

### 📃 Motivating Example

Every project that utilizes import maps.

### 💻 Use Cases

1. What do you want to use this for?

Simplifying my configuration in projects that contain both Node and Deno workspaces.

2. What shortcomings exist with current approaches?

One needs to re-specify their aliases in numerous places.

3. What workarounds are you using in the meantime?

N/A

Inizia leggendo la gestione esistente di compilerOptions per paths e il comportamento di module-resolution che import maps influenzerebbero. Confronta l’opzione importMap proposta con gli aliases e gli scopes di import-map, quindi definisci la configurazione supportata e il comportamento di compatibilità prima dell’implementazione; il lavoro è completato quando esiste un design revisionato con copertura del caso d’uso di workspace Node e Deno indicato.
