问题 I have an Angular 6.x app running perfectly in Chrome. The problem is when trying to run it in IE 11, I'm getting the error: Error: Invalid argument. at DefaultDomRenderer2.prototype.setProperty... Already tried all answers in StackOverflow that I could find with no help.

问题 Unfortunately I have to support IE11. I create my map with this code (polyfill for .entries already used): const map = new Map(Object.entries(array)); but because of IE11 not supporting the iterable constructor the Map is empty.
