WordPress Gutenberg is a content editor that was first introduced in WordPress 5.0 in 2018. Gutenberg brings the concept of blocks to WordPress, allowing users to easily create and edit site content using a set of preset blocks or by creating their own.

Gutenberg blocks can be created in a variety of programming languages, including PHP and JavaScript, using the React library. Using React-based Gutenberg blocks has many advantages over PHP, which can be categorized as follows:

Gutenberg is clearer code structure

Gutenberg on React allows developers to create blocks with cleaner code than when using PHP. React blocks have a more logical structure and are broken down into individual components, making them easier to understand and maintain.

Gutenberg is greater flexibility and extensibility

React is a powerful JavaScript library that provides many tools and features for creating user interfaces. This allows developers to create more flexible and powerful units that are easier to extend and improve.

Gutenberg is improved performance and optimization

React is designed with performance in mind and provides many DOM optimization tools. This improves block performance by making blocks faster and more responsive.

Gutenberg has many themes and templates

React is one of the most popular frameworks for creating user interfaces, with a huge community of developers and tools. This provides more support and options for building and using React-based units.

Gutenberg is a better Mobile Support

React has built-in support for mobile devices, allowing developers to create blocks that better adapt to different devices and screens.

Using React to create Gutenberg blocks allows developers to create more productive and flexible blocks that are easier to maintain and extend. It also makes it easier to create blocks that are adaptive and mobile-friendly.

In addition, React-based blocks are easily scalable and can be used in other projects and platforms, making them more versatile.

Despite these advantages, using React to create Gutenberg blocks also has its drawbacks. For example, it requires more time and effort to learn and get started, especially for those who are already familiar with PHP.

In addition, using React may require additional infrastructure and training because it requires the use of Node.js and other tools needed to develop and compile it.

Overall, using Gutenberg blocks on React may be a better choice for developers who want to build more flexible, productive, and scalable sites. However, the choice of programming language depends on the specific needs and capabilities of the project and requires evaluation by the developer.
