vuepress is a direct dependency of this project, and it is very likely causing it to break. If other packages depend on yours, this update is probably also breaking those in turn.

如题:面试时候手写reduce的话
是否需要考虑第二个参数的默认值 以及参数的函数类型和this等
不按规范去写是否可以通过面试
https://github.com/yhlben/blog/blob/master/docs/interview/2019-9.md
const array1 = [1, 2, 3, 4];
const reducer = (accumulator, currentValue) => accumulator + currentValue;
console.log(array1.reduce(reducer));
// NaN
这样的话initialValue是必传选项。是否与基本规范不符。
如果initialValue改为从arguments中取的话,当不传initialValue时候,需要判断当前的this。
然后就是想问一下,这个手写reduce的话,面试官想要得到的是哪些点呢?
