Specific examples:
- The information you enter in the form is displayed in real time.
- Changes to data are reflected immediately on screen
This feature allows users to see the results of their actions immediately, so they don't feel stressed. This is a major advantage, especially in situations where real-time performance is required, such as online stores and chat apps.
4. Small size and light weight
Vue.js is one of the lightest libraries out there. This is very important for fast page loading speed. If you use a heavy library, it can take a long time for users to open a page, which can be frustrating.
Lightness points:
- Fast initial loading
- It's lightweight and works well on mobile devices
This characteristic creates a comfortable environment for users, especially those on mobile devices. A fast app leaves a good impression on users, which may lead to increased repeat visits.
5. Good integration with other libraries
Vue.js can be easily combined with other libraries and tools. For example, you can use it with tools for managing data or libraries for state management. This flexibility gives you more freedom in your development.
Examples:
- State Management with Vuex
- Integrating with API using Axios
In this way, Vue.js can be combined with other tools to create even more powerful applications. Developers can choose the tools that best suit their needs and progress their projects more efficiently.

These features allow developers to spend less time wasting time and more time focusing on what matters, which helps teams work faster and keeps the whole project moving smoothly.
8 Disadvantages of JavaScript Vue.js
1. Concerns about large-scale apps
Vue.js is very suitable for small projects due to its simplicity, but it can be a little scary in larger applications, especially as the number of components increases and it can become difficult to manage.
Specific concerns:
- More component dependencies
- State management can be complicated
For these reasons, it is important to carefully design a large-scale app. Choosing the right architecture will help you develop it smoothly.
2. SEO is essential
Vue.js is very useful for creating single page applications (SPAs), but you need to be careful when it comes to search engine optimization (SEO). For regular websites, search engines can easily retrieve content because HTML is returned directly from the server. However, dynamic applications like Vue.js need to execute JavaScript, so search engines may not be able to index the content properly.
Specific issues:
- If search engines can't run JavaScript, they can't retrieve information.
- Your page may not be indexed properly and therefore may not appear in search results.
To solve this problem, it is recommended to use Server-Side Rendering (SSR), where pages are generated on the server side and the content is easily accessible to search engines. In Vue.js, this feature can be easily implemented by using a framework called Nuxt.js.
3. It can be expensive to learn
Although Vue.js is considered relatively easy to learn, it can still have a certain learning curve compared to other frameworks and libraries, especially as it can take time to get used to Vue.js-specific concepts and features.
Difficulty in learning:
- You need to understand related libraries such as Vuex and Vue Router.
- Passing data between components and managing state can be difficult
For this reason, it is important to learn the basics thoroughly, especially for beginners. Using official documentation and tutorials will help you progress smoothly. Support from the community is also very helpful.
4. Impact of the upgrade
Vue.js regularly releases new versions, which add new features, but can cause compatibility issues with existing code. Especially in large projects, changes that come with version upgrades can affect development.
Specific impacts:
- Requires work when migrating to new versions
- This can lead to incompatible code.
For this reason, it is important to properly manage versions from the early stages of the project. Also, when upgrading, it is a good idea to check the release notes to understand what changes have been made.
5. Insufficient documentation
Vue.js is a very popular framework, but not all of its features are well documented, especially when it comes to new features and libraries.
Problem:
- Missing information about a particular feature
- Sometimes you have to rely on community information
For this reason, you may need to gather information yourself. It is important to gather information not only from official documentation, but also from blogs, forums, GitHub, and other resources. In particular, the experiences of other developers can be very helpful.
6. Ecosystem Complexity
The Vue.js ecosystem is very rich, but at the same time it is also complicated, especially with the various plugins and libraries available, which can make it difficult to choose which one to use.
Specific concerns:
- Choosing a plugin is difficult
- There may be compatibility issues
In situations like these, it’s important to do your research to choose the best tools for your project, especially choosing reliable plugins with community reviews and documentation.
7. Difficulty in managing state
Vue.js requires a mechanism for managing the state of your application. Managing state can be difficult, especially when multiple components are involved. Vuex can solve this problem, but it requires some learning to understand.
Problem:
- Difficult to manage state
- Vuex can be complicated to set up and design.
A solid state management design will make the entire application run smoothly. If you are using Vuex for the first time, we recommend that you start with a simple project and gradually challenge yourself to manage more complex state management.
8. Depends on developer skills
Vue.js is highly dependent on the skills of the developer, especially if you don't understand project design, coding style, and best practices, you may not be able to use it effectively.
Specific concerns:
- Inexperienced developers may find the code inefficient.
- Lack of knowledge sharing within a team can have a negative impact on a project.
For this reason, it is necessary for the entire team to improve their skills. It is important to learn from each other through regular study sessions and code reviews. This will improve the development skills of the entire team and make the project more likely to succeed.
Comparison of JavaScript Vue.js with other libraries
Difference between Vue.js and React
Vue.js and React are both popular front-end libraries, but they have some differences: Vue.js uses HTML-based templates, while React uses an extended JavaScript syntax called JSX, which often makes Vue.js feel more intuitive.
Main differences:
- Vue.js uses templates, React uses JSX
- Vue.js makes data binding easy, React can be difficult to manage state
Also, Vue.js is suitable for small projects because it is easy to manage components, while React can perform better in large applications. Therefore, it is important to choose the right library depending on the size and requirements of your project.
Difference between Vue.js and Angular
Vue.js and Angular are also popular front-end frameworks, but they take very different approaches: Angular is a full-stack framework developed by Google that offers advanced features like type safety and dependency injection, while Vue.js is lightweight and focuses on simplicity.
Main differences:
- Angular is a full-stack framework, Vue.js is a lightweight library
- Angular is more complex but has more features, Vue.js is simple but flexible
Therefore, you need to decide which one is more suitable depending on the needs of your project. Angular is often more suitable for large enterprise applications, while Vue.js allows for fast development.
Difference between Vue.js and jQuery
jQuery is an older library designed to make DOM manipulation easy, but Vue.js is a framework designed to serve the needs of modern front-end development, offering a data-binding, component-oriented approach.
Main differences:
- approach: jQuery is primarily focused on DOM manipulation and employs a procedural programming style, whereas Vue.js emphasizes clearly defining the structure of your application through state management and a component-based architecture.
- performance: Vue.js uses a virtual DOM and efficiently updates only what is needed, whereas jQuery manipulates the DOM directly, which can result in poor performance, especially in large applications.
- Maintainability: Vue.js's component-based design allows for high code reuse and improves application maintainability. As the code grows, jQuery's dependency and state management can become complicated.
This makes Vue.js a better choice when building modern web applications, especially when dynamic user interfaces and large-scale data management are required.
