@emotion/微弱的记忆

使用弱映射的记忆函数

安装

yarn add @emotion/weak-memoize

使用量

因为 @emotion/weak-memoize 使用弱兆(弱兆),所以参数必须是非原始类型,例如对象,函数,阵列等. 函数传递到 weakMemoize 还必须只接受一个论点.

import weakMemoize from '@emotion/weak-memoize'

let doThing = weakMemoize(({ someProperty }) => {
  return { newName: someProperty }
})

let obj = { someProperty: true }

let firstResult = doThing(obj)

let secondResult = doThing(obj)

firstResult === secondResult // true

let newObj = { someProperty: true }

let thirdResult = doThing(newObj)

thirdResult === firstResult // false
