inline function method refactoring

Suggestion

I would like a refactoring that inlines a function from

1: function foo() { return 42; }
2: function bar() { const meaningOfLife = foo(); }

to

1: function bar() { const meaningOfLife = 42; }

Use Cases

This is a very common refactoring and thus widely used while cleaning up code.

Examples

In the above code sample, block 1, line 1: selecting foo, the user should be able to inline this function to every occurence and optionally delete the function definition.

In the above code sample, block 1, line 2: selecting foo, the user should be able to inline the function to this occurence, and, if it's the only one, optionally delete the function definition.

I am not sure how the option can be handled in vscode. Eclipse brings up a pop-up with the two options, but afaik vs code tries to be minimalist.

Checklist

My suggestion meets these guidelines:

• This wouldn't change the runtime behavior of existing JavaScript code
• This wouldn't be a breaking change in existing TypeScript / JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. new expression-level syntax)

Inizia dagli esempi di funzioni inline e dal comportamento richiesto per selezionare una dichiarazione di funzione o un sito di chiamata. Esamina come l’editor TypeScript gestisce attualmente i refactoring e determina la semantica per sostituire le occorrenze, preservare il comportamento e rimuovere facoltativamente la definizione. L’issue non indica file né test, quindi è ancora necessario identificare il punto di ingresso dell’implementazione e i controlli di completamento.
