  • Returns whether the type is a generic and what its constraint is. *
  • If the type is not a generic, `isTypeParameter` will be `false`, and
  • `constraintType` will be the same as the input type. *

  • `true`, and `constraintType` will be the constraint type. *
  • If the type is a generic, but it is not constrained, `constraintType` will be
  • `undefined` (rather than an `unknown` type), due to https://github.com/microsoft/TypeScript/issues/60475 *
  • Successor to {@link getConstrainedTypeAtLocation} due to https://github.com/typescript-eslint/typescript-eslint/issues/10438 *

Note: When called from ast.KindPropertyAccessExpression or ast.KindElementAccessExpression listeners, the returned property is guaranteed to be non-nil because:
