spread operator for enum
See original GitHub issueSearch 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.

This can be done right now with
Object.values
:This would be cool, if added anytime soon. As of now the suggestion of @nickbclifford does the job
console.log(...Object.values(Enum))
