Add refactoring action to annotate a variable or a function signature component with its inferred type

Hi, I'm using latest stable VSCode / latest nightly TS and I'm not sure if codefixes and refactorings have been implemented there yet, in any case, having a refactoring option to take any variable which receives an implicit inferred type, say, through a function call:

function test(): number[] {
  // ...
}

let x = test(); 

And being able to right-click x and invoke an action like Annotate with inferred type (or Extract inferred type), such that the resulting statement would look like:

let x: number[] = test();

could be very useful!

Inizia con il comportamento di codefix e refactoring di TypeScript utilizzato da VSCode, riproducendo l’esempio con l’ultima versione nightly di TypeScript. Definisci come l’azione deve gestire i tipi delle variabili inferiti e i componenti delle firme delle funzioni, quindi verifica che produca annotazioni come let x: number[] = test();.
