Por mucho que nos gustaría escribir código perfecto y sin errores, es una empresa casi imposible. Por eso necesitamos una forma de tratar los problemas inevitables de nuestro código.

Sin embargo, combinar las excepciones con un enfoque funcional puede ser un verdadero reto, ya que las técnicas están plagadas de consideraciones y requisitos. Aunque existen bibliotecas de terceros que pueden ayudarte con esto, es posible que no quieras depender únicamente de ellas a largo plazo, incurriendo en deuda técnica debido a una nueva dependencia, en lugar de adaptarte a un enfoque más funcional en general.
Este capítulo te mostrará los distintos tipos de Excepciones y su impacto en la programación funcional con lambdas. Aprenderás a manejar las Excepciones en las lambdas, así como formas alternativas de enfocar las interrupciones del flujo de control en un contexto funcional.
