• Would you like to work on a fix?

How are you using Babel?

babel-loader (webpack)

Input code

export enum Permission {
  'CREATE_INSTANT_INVITE' = 1 << 0,
  'KICK_MEMBERS' = 1 << 1,
  // ...
  'USE_PRIVATE_THREADS' = 1 << 36,
  'USE_EXTERNAL_STICKERS' = 1 << 37,
}

Configuration file name

No response

Configuration

This problem exists in any configuration.

Current and expected behavior

Current: it will overflow if the value <= 2^31

export let Permission;
(function (Permission) {
  Permission[Permission["CREATE_INSTANT_INVITE"] = 1] = "CREATE_INSTANT_INVITE";
  Permission[Permission["KICK_MEMBERS"] = 2] = "KICK_MEMBERS";
  Permission[Permission["USE_PRIVATE_THREADS"] = 16] = "USE_PRIVATE_THREADS";
  Permission[Permission["USE_EXTERNAL_STICKERS"] = 32] = "USE_EXTERNAL_STICKERS";
})(Permission || (Permission = {}));

Excepted:

Environment

• Babel: 7.19.0
• Node: 16.16.0
• Npm: 8.19.2
• Yarn: 1.22.19

Possible solution

Using number in JavaScript for operation?
