spread operator for enum

Search Terms

• Enum
• Spread operator

Suggestion

I would like to use the spread operator to spread the values (or maybe the keys) of an enum.

Use Cases

I want to use this to check or print available types of enum type.

Examples

enum TestStatus{
    PENDING,
    ACCEPTED,
    WRONG_ANSWER
}
console.log(...TestStatus); // prints: "PENDING"  "ACCEPTED"  "WRONG_ANSEWR"

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.

Inizia con l’esempio di enum e spread-operator nell’issue, quindi esamina gli obiettivi di progettazione di TypeScript collegati. Chiarisci se lo spread debba esporre le chiavi dell’enum, i valori o entrambi, e definisci il comportamento previsto per l’esempio mostrato. Il lavoro è completato quando la proposta presenta un design semantico concordato e soddisfa la checklist indicata senza modificare il comportamento esistente del runtime JavaScript.
