What improvements does Vue.js have over Angular.js?

Angular.js and Vue.js are two front-end frameworks that are very closely related. According to the official website of Vue.js, in its early development, the source of inspiration was Angular.js. . In many ways, Vue.js is just like the old Chinese saying, "The best is better than the blue." Today, K will discuss with you from the following aspects, in which aspects Vue.js is "better than blue".

(1) Simple operation

This is the most outstanding method of Vue.js in K's opinion. Vue.js is committed to the presentation of view layer, which makes it very easy to integrate with other projects. This is also Make it easier to "embed" other libraries or projects. In terms of writing, K also prefers Vue.js, whether it is various data, method binding, etc. This is difficult for Angular.js to match.

(2) One-way data flow

This It is the mandatory one-way data flow between different modules that Vue.js has. It is a major feature of Vue.js that is different from Angular.js. The one-way data flow data binding method provided by Vue.js makes it easier for programmers to understand and control the direction of data when operating.

(3) Instructions and Components

In Vue In .js, strengthens the distinction between instructions and components: instructions only encapsulate DOM operations, while components represent a self-sufficient independent unit - with its own views and data logic. In Angular, there are many confusions between the two.

(4) Optimization is simpler

Vue. Data changes in js are relatively independent (unless there are particularly clear dependencies), while in Angular.js, changes to a certain piece of data in a scope will cause the watcher to react to this effect again domain is updated. Relatively speaking, the latter will spend more time optimizing data updates, especially when there are a large number of scopes, while the former will not have this problem at all.

The above four points are the differences that K felt after initially learning Vue.js and Angular.js. In fact, to a certain extent, the two are equal. Each of them has its irreplaceable part. Perhaps at some time in the future, there will be another framework with stronger comprehensive capabilities than the two.
