IE11 / Windows 10 =＆gt;对象不支持属性或方法＆＃39;包括＆＃39;

Question

在Windows 10的IE11中，我得到了Object doesn't support property or method 'includes' error on Cookie.set('something', null)。以前我有Cookie.remove('something')而且出现了同样的错误。

  Cookie = require('js-cookie')
  Cookies.set('save_lead', null)
  // used to be:
  // Cookies.remove('save_lead')

我使用array-includes npm包找到了解决方法。乍一看，看起来它只是给你一个替换来调用arr.includes('foo')，但它也允许一个垫片。

来自github自述文件：

var includes = require('array-includes');
var assert = require('assert');
/* when Array#includes is not present */
delete Array.prototype.includes;
var shimmedIncludes = includes.shim();

assert.equal(shimmedIncludes, includes.getPolyfill());
assert.deepEqual(arr.includes('foo', 1), includes(arr, 'foo', 1));

希望它可以帮助他人。
