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
> {
  // ...
}
