**FastAPI** se basa completamente en estas anotaciones de tipos, dándole muchas ventajas y beneficios.

Pero incluso si nunca usas **FastAPI**, te beneficiaría aprender un poco sobre ellas.

Comencemos con un ejemplo simple:

                Element child = buildChildren.get(i);
                if ("pluginManagement".equals(child.name())) {
                    pluginManagementIndex = i;
                } else if ("plugins".equals(child.name())) {
                    pluginsIndex = i;
                }
            }

            assertTrue(pluginsIndex >= 0, "plugins should be present");
