# E0265: missing comma between generic parameters

In a TypeScript generic class, function, or type alias, the generic parameter list is a comma-separated list of variables surrounded by `<` and `>`. It is a syntax error to omit a comma between generic parameters:

    class MagicMap<
      Key extends string|number
      Value
    > {
      // ...
    }

To fix this error, write a comma between the two generic parameters:

    class MagicMap<
      Key extends string|number,
      Value
    > {
      // ...
    }

Introduced in quick-lint-js version 2.8.0.
