Refactor to extract a part of type property into a new type

Suggestion

It's common to convert a part of properties into new type when we got too many related property.

Could we provide an automatic way to do this?

Examples

//from
interface A {
    /*a*/f1: string
    f2: string/*b*/

    a1: number
}

// to
interface NewType {
    f1: string
    f2: string
}

interface A {
    /*RENAME*/ newProperty: NewType

    a1: number
}

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing 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. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

ソースファイル、テスト、エントリポイントは指定されていません。まず、要求されている TypeScript インターフェースの変換と既存のリファクタリング機能を確認してください。完了条件は、図示された新しい型とプロパティの構造を生成する自動抽出ワークフローが定義されていることです。
