# E0250: enum member name cannot be numeric

TypeScript enum members can be named using an identifier or a string literal. It is a syntax error to name an enum member using a number literal:

    enum LogLevel {
      ERROR = 0,
      WARNING = 1,
      INFO = 2,

      // For array-like access:
      0 = 0,
      1 = 1,
      2 = 2,
    }

To fix this error, replace the enum with an object:

    const LogLevel = {
      ERROR: 0,
      WARNING: 1,
      INFO: 2,

      // For array-like access:
      0: 0,
      1: 1,
      2: 2,
    } as const;

Introduced in quick-lint-js version 2.7.0.
