前端开发策略：框架还是纯 JavaScript？_AI阅读总结 — 包阅AI

A relatively large variety of frontend frameworks are implemented in the JavaScript programming language. Occasionally, though, it becomes challenging to determine which should be applied to a new project. Or the state of the web platform is such that we do not need any framework at all.

Frameworks provide web designers essential features. Likewise, there are cases when designers can solve a problem using only JavaScript.

A frontend framework is a package of code written to solve common issues such as data binding and retrieval, routing, code organization and other features that contemporary applications use. Frontend frameworks are great instruments for fast mobilization and web development in general.

A frontend framework helps structure and master code, and it can handle everything a reasonable application requires on the client side.

When to Use a Frontend Framework

To determine if you need a framework, ask yourself: “Is it possible to build that without having a framework to start with?” In cases where the task is rather simple, doesn’t use data fetching, binding or complex routing, a framework might be unnecessary.

This is a program in which some developers open a blank HTML file and code the entire project from the drawing board. Such projects are appropriate for a personal site or portfolio, which might be a great idea because, in this case, there are no specific demands, and the result will be rather quick.

However, there are cases when using a framework will deliver extensive gains.

Benefits of Frontend JavaScript Framework

Check the benefits of using JavaScript frameworks for frontend development to boost web design skills.

Simplified Syntax and Structure

JavaScript frameworks define the development pattern as having more easy syntax with pieces of code already written in them. This structure offers the developers an easy way to adopt the framework and build applications without many lines of extra code that form the main framework. Libraries such as Angular, React and Vue.js offer many rules and recommendations that make the work more efficient and minimize the time needed to study the code by the team’s new members.

Modular Code Organization

Frameworks make writing modular code easier by dividing the application into small and interchangeable parts. This modularity helps developers write good, structured code and helps team members work together smoothly. Since each component can be built, tested and maintained separately, it leads to cleaner codebases for maintenance.

Reusable Components

JavaScript frontend frameworks also can help you develop modules — another strength. These components can be reused within one application or even used for another project. This reusability reduces the time needed to develop a project, standardizes the body of written code and cuts across the forms of redundancy.

Rich Ecosystem and Libraries

JavaScript frameworks have developed complex environments filled with libraries, tools and plugins that are used along with the frameworks. The mentioned resources can be of paramount assistance to developers because they can enhance their applications with ready-made features and functions. For example, in React, there is no standard way to manage the state, route the application or handle forms. However, there is a long list of third-party libraries with solutions to these problems that can be easily incorporated into the application.

Virtual DOM and Efficient Rendering

Libraries like Preact, Next.js and Vue.js use virtual the Document Object Model (DOM) to increase rendering speed. Virtual DOM is a layer over the actual DOM and rarely directly manipulates the application’s DOM. This approach reduces the number of expensive DOM operations, making updates faster and even more efficient when dealing with enhanced and dynamic applications.

Code Splitting and Lazy Loading

JavaScript frameworks enable more complex strategies, such as code splitting and lazy loading, which enhance the application’s efficiency. Code splitting helps break the application code into pieces that can be loaded on demand, which will, in turn, help minimize the loading time. Lazy loading also boosts productivity by loading only the required components and resources when required, thus enhancing the application’s usability.

Standardized Development Practices

Applying a JavaScript framework contributes to the preparation of an entire team by implementing a specific set of standards. These frameworks come with rules and standards and recommend ways or methods in which specific projects should be coded and structured. These make coding more accessible for developers looking at the code in the later stages of development to read and maintain.

Adaptability to Different Project Sizes

Developed for versatility, JavaScript frameworks can be used in large or small enterprises that are complex in equal measures. These frameworks are suitable for any application — a simple application with only one page and an extensive enterprise application with multiple levels of complexity. For developers, it is possible to begin simply yet progressively expanding the apps without encountering monumental architectural shifts.

Integration with Modern Development Tools

Current JavaScript frameworks are flexible and can easily be incorporated into the different development tools and development life cycles. They support build tools and package managers such as npm and Yarn. They also enrich the development process by eliminating tedious activities, coordinating dependencies and arranging the construction process, which boosts work productivity.

Conclusion

JavaScript is the future of web development. Everything depends on the selected framework and the specialized functions and options for cloud hosting. JavaScript is used for client-side scripting and writing server-side or game-server scripts or socket programming. However, since the browser knows only one language, JavaScript has earned its popularity.
