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)

Beginnen Sie mit den Beispielen für Inline-Funktionen und dem angeforderten Verhalten zur Auswahl einer Funktionsdeklaration oder Aufrufstelle. Überprüfen Sie, wie der TypeScript-Editor derzeit Refactorings verarbeitet, und bestimmen Sie die Semantik für das Ersetzen von Vorkommen, das Beibehalten des Verhaltens und das optionale Entfernen der Definition. Im Issue werden keine Dateien oder Tests genannt, daher müssen der Einstiegspunkt der Implementierung und die Prüfungen für den Abschluss noch ermittelt werden.
