Function composition allows us to build up powerful functions from smaller, more focused functions. In this lesson we'll demystify how function composition works by building our owncomposeandcomposeAllfunctions. //__test__import {add, inc, dbl, addInc, addIncDbl} from'../function/custom-compose...
函数组合(Function composition) 在计算机科学中,函数组合是将多个简单的函数,组合成一个更复杂的函数的行为或机制。每个函数的执行结果,作为参数传递给下一个函数,最后一个函数的执行结果就是整个函数的结果。 如下图,可以把函数的处理过程想象成一个管道,a表示输入值,b表示输出值,fn表示处理数据的管道。 如果处理...
This chapter builds on the idea of first-class functions by explaining how and why one builds functions on the fly. It explores various ways to facilitate function “composition”—snapping together functions like Lego blocks to build richer functionality from parts. The Essence of Functional Compos...
Function currying allows and encourages you to compartmentalize complex functionality into smaller and easier to reason about parts. These smaller units of logic are dramatically easier to understand and test, and then your application becomes a nice and clean composition of the smaller parts. varsendM...

使用Composition api的位置被称为setup setup组件选项 setup 组件选项在创建组件之前执行,一旦 props 被解析,并充当合成 API 的入口点。 注意:由于在执行 setup 时尚未创建组件实例,因此在 setup 选项中没有 this。这意味着,除了 props 之外,你将无法访问组件中声明的任何属性——本地状态、计算属性或方法。
