Enum allows numeric keys with leading 0s about typescript HOT 5 CLOSED

It's not about whether or not you can write TestEnum.Foo (e.g. "Foo Bar" = "works" is also legal) but whether the name of a member could potentially clash with a reverse mapping, so keys that overlap with the canonical string representation of a number are intentionally not allowed.

Oh okay! Thank you for the information, and sorry for the wrong assumption and the disturbance :D

from typescript.

This isn't a bug: all of the following are intentionally allowed:

enum TestEnum {
  "1e2",
  "3.40",
  ".567",
  "88888888888888888"
}

It's for the reason @fatcerberus said; while those can be parsed as numbers, they are not how those numbers would be represented when converted to strings, so they cannot conflict with reverse mappings. If there were no reverse mappings, all numeric keys would be allowed.

Bracket notation is still valid: TestEnum["00"]

from typescript.

Yeah, but in that sense TestEnum["0"] would also be valid.
