266. 认知负荷至关重要

from 知为谁 · host 知为谁

这些资源主要讨论认知负荷在软件开发中的重要性,将其定义为开发者完成任务所需的思考量。文章指出,过高的认知负荷会增加混乱、时间和金钱成本,并将其分为内在负荷(任务固有难度)和外在负荷(信息呈现方式造成)。主要关注点在于减少外在认知负荷,通过提供具体的编程实践示例,如简化复杂的条件语句、避免深层继承、使用深模块而非浅模块,以及优先选择自描述性字符串而非抽象的HTTP状态码等。此外,它还强调避免过度遵循某些“最佳实践”,如DRY原则的滥用、对框架的过度依赖、僵化的分层架构以及对领域驱动设计(DDD)的误解,认为这些都可能无意中增加不必要的认知负担。最终,文章呼吁开发者专注于降低超出工作本身内在难度的认知负荷,以提高代码的可理解性和可维护性。内容来源:https://github.com/zakirullin/cognitive-load
