会不会是 polyfill 有些问题,我这边配置 targets 为 { ie: 11 } 之后,可以在 IE 9 里跑了

排查过程

仔细排查了下,发现和 plugin-model 依赖的 lodash.isequal 有关,他里面有这么一段,

if ((DataView && getTag(new DataView(new ArrayBuffer(1))) != dataViewTag) ||
    (Map && getTag(new Map) != mapTag) ||
    (Promise && getTag(Promise.resolve()) != promiseTag) ||
    (Set && getTag(new Set) != setTag) ||
    (WeakMap && getTag(new WeakMap) != weakMapTag)) {
  // ..
}

其中 new ArrayBuffer(1) 会报错,猜测原因可能是 1) polyfill 有问题 2) ie9 本身对于 ArrayBuffer 的处理问题。

他们引入的补丁方案差异如下,

// ie9
es.array-buffer.constructor { "edge":"13", "ie":"9", "ios":"10", "safari":"10" }
es.array-buffer.is-view { "ie":"9" }
es.array-buffer.slice { "ie":"9", "ios":"10", "safari":"10" }

// ie11
es.array-buffer.constructor { "edge":"13", "ie":"11", "ios":"10", "safari":"10" }
es.array-buffer.slice { "ios":"10", "safari":"10" }

ie9 多一个 is-view 的实现,但看起来不是关键问题。

建议方案

lodash.isequal 实现太复杂了,尺寸也大,有 50K 左右,换个方案吧。

@sorrycc 请问下有解决方案吗? 升级到哪个plugin-model版本能解决呢?我们急需支持IE
