Do I need to learn vue to learn vue2?

With the popularity of the front-end and back-end separation model, front-end frameworks are becoming more and more diversified. Vue.js is one of the most popular front-end frameworks currently. The responsive nature of Vue.js using the MVVM pattern makes it easier for developers to develop efficient, responsive front-end single-page applications (SPA). But in the update cycle of Vue.js, the Vue.js 2.x version has now been launched. So, if you want to learn Vue.js, can you directly learn Vue.js 2.x version?

First, what are the differences between Vue.js 2.x and 1.x?

• Faster: Vue.js 2 optimizes its internal implementation so it can significantly improve performance.
• Better template rendering: Vue.js 2 adds some new directives, such as v-for and v-if that can be used on the same element.
• Better cross-component data transmission: Vue.js 2 adds provide and inject for better component communication.
• Better developer experience: Vue.js 2 encourages the use of TypeScript for development and also provides better syntax highlighting and prompts for single-file components (.vue).

It is not difficult to see that Vue.js 2.x is superior to the 1.x version, including some new features, better performance, better rendering mechanism, etc. Therefore, if you have the energy and time, we recommend that you directly learn the Vue.js 2.x version.

Second, should you learn Vue.js version 1.x?

In the future, you may find yourself needing to maintain or update some projects that already use Vue.js 1.x or earlier. In this case, learning both Vue.js 1.x and Vue.js 2.x is very useful and necessary. Therefore, you can learn the Vue.js 2.x version first, and then schedule time to learn the earlier versions. However, if you are a developer who has just started learning the Vue.js framework, it is recommended to start learning Vue.js 2.x directly, because this version has a higher usage rate and is more in line with today's business needs.

Third, how to learn Vue.js 2.x?

If you want to get started with Vue.js 2.x quickly, you can consider the following steps:

• Read the Vue.js official guide: The Vue.js official website provides guides and sample code and other related information, which is very convenient for novices to get started quickly.
• Learn responsive features: The biggest feature of Vue.js is responsive programming. You need to learn responsive data, calculated properties, observers and other related knowledge.
• Learn components and single-file structure in Vue.js: Vue.js provides support for componentization and single-file components, which can allow us to simplify and optimize our project structure.
• Learn Vue.js routing: Routing is a necessary component for building Vue.js single-page applications. Vue.js supports Vue-Router to help us manage complex routing.

Conclusion

In general, if you are a beginner in front-end development or want to further engage in Vue.js development, it is recommended to learn Vue.js 2.x directly. , because it already includes all the content of Vue.js 1.x, while adding some new features, and is widely supported and recognized. And if you are planning to take over or maintain some previous Vue.js projects, you might as well learn some relevant knowledge of Vue.js 1.x first. No matter which version you choose, be sure to keep learning, practicing, and exploring.
