Ie11 reports an error unhandled promise rejection typeerror: the object does not support

The problem of ie11 is the biggest problem. At this time, you should check the most likely place of the problem step by step
I make this error because I use the following code when making type judgment:
toString. Call (svalue)==‘ [object date] ‘
such a writing method is not recognized in ie, and an unhandled promise rejection typeerror will be reported: the object does not support it, so it is necessary to change the writing method

Object.prototype.toString.call(sValue) !== ‘ [object date] ‘
this way of writing is recognized by ie

The solution

SRC /index.js
add the following and put it on the first line

import 'react-app-polyfill/ie9';

Json
find browserslist and add ie9 which is the above support

"browserslist" {
	"production": [

The error in the Internet Explorer console, the solution:
Open the /node_modules/react - dev - utils/webpackHotDevClient js , in the following code to add slashes: true,

goes into the node_moudles folder, delete all contents of the . Cache folder, and clear the cache in Internet explorer.
SCRIPT5009: 'Map' is File: Map is undefined e.chunk.js, Line: 2340,0 Column: 3
I did not solve this error by myself. Due to the company project, NPM install cannot be run on the server's Intranet. Therefore, I provide ideas and hope you can solve it perfectly.
