Does vue support ie6?

vue does not support ie6; vue officially states that it supports ie8 or above. Reasons for not supporting: 1. IE8 and below versions do not support the "Object.defineProperty" method, but this method is necessary for Vue to implement responsiveness; 2. Vue requires the support of Promise, and IE8 and below versions do not support Promsie.

As can be seen from the Vue official website: Vue does not support IE6.

Vue does not support IE8 and lower versions because Vue uses ECMAScript 5 features that IE8 and lower versions cannot emulate. But it supports all ECMAScript 5-compatible browsers.

For example:

• Vue.js will use Object.defineProperty to convert all these properties into getters/setters for all data that implements two-way binding. Object.defineProperty is a feature in ES5 that cannot be shimmed, which is why Vue does not support IE8 and lower browsers.

  Note here: Object.defineProperty is a method that cannot be implemented through the underlay and is related to the browser itself, so Vue fundamentally cannot support IE8;

• Vue requires Promise support, and IE8 and below also do not support Promsie.

Extended information:

Object.defineProperty()

This method allows precise addition or modification of the properties of the object. Generally, we add properties to objects by assigning values ​​to create and display them in the property enumeration (for...in or Object.keys method), but the property values ​​added in this way can be changed or deleted. Using Object.defineProperty() allows changing the default settings for these additional details. For example, by default, property values ​​added using Object.defineProperty() are immutable.
