This article will explain in detail whether vuejs can support ie678. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Vuejs does not support ie678 because Vue.js uses ECMAScript5 features that IE8 and the following versions cannot simulate, such as "Object.defineProperty ()" and "Promise".

The operating environment of this tutorial: windows7 system, vue2.9.6 version, DELL G3 computer.

Vue supports IE8 and the following versions, that is, ie6, ie7, and ie8 are not supported.

Then why? Reason:

Vue uses ECMAScript 5 features that cannot be simulated by IE8 and below. In other words: Vue supports all ECMAScript 5-compliant browsers.

But what are the specific features?

Object.defineProperty ()

This method allows precise addition or modification of the properties of an object. In general, we add properties to an object by assigning values to create and display in the property enumeration (for... In or Object.keys method), but the value of the property added in this way can be changed or deleted. Using Object.defineProperty () allows you to change the default settings for these extra details. For example, by default, the value of the property incremented with Object.defineProperty () is immutable.

Search for "Object.defineProperty" in the vue source code:

You can see that there are five matches, which means that "Object.defineProperty ()" is used in five places in vue.

The search version is: Vue.js v1.0.26

Browser support for Object.defineProperty ():

It can be seen that the support situation is IE9 or above.

Vue officials have an explanation for this:

Promise

Vue needs the support of Promise, and IE8 does not support Promsie either.
