《lodash源码分析之every》

源码分析

overEvery 接收一组断言函数 iteratees ,返回一个函数,在调用这个函数时,会依次调用断言函数,并将函数的参数作为断言函数的参数传入,如果所有的断言函数都为真值,则返回 true ,否则返回 false

源码如下:

function overEvery(iteratees) {
  return function(...args) {
    return every(iteratees, (iteratee) => iteratee.apply(this, args))
  }
}

其实就是调用 every 来遍历断言函数,如果其中一个得到的是假值,则会中止遍历。
