Cómo obtener todos los objetos y contar booleanos (JS)

Que sea así por ejemplo:

 let data = { first: { surname: 'Miller', age: 37, gender: 'male', stealer: true }, second: { surname: 'Connor', age: 28, gender: 'male', stealer: true }, third: { surname: 'Smith', age: 13, gender: 'female', stealer: false } }

¿Cómo puedo obtener todo a la vez y contar booleanos de false, sin necesidad de ingresar manualmente cada uno individualmente?

Puede usar Object.values para recuperar los valores como una matriz y Array.prototype.reduce para contar:

 let data = { first: { surname: 'Miller', age: 37, gender: 'male', stealer: true }, second: { surname: 'Connor', age: 28, gender: 'male', stealer: true }, third: { surname: 'Smith', age: 13, gender: 'female', stealer: false } }; const result = Object.values(data).flatMap(el => Object.values(el)).reduce((acc, el) => acc + (el === false), 0); console.log(result);
