Jamstack is a modern web development architecture that emphasizes performance, security, and scalability. The term stands for JavaScript, APIs, and Markup. In this approach, static content is generated at build time, while dynamic features are handled through APIs, allowing developers to create fast and efficient websites. By decoupling the front end from the back end, Jamstack enables developers to use various tools and services for each part of the application. This flexibility allows for easier updates, improved load times, and enhanced user experiences, making it a popular choice for building websites and applications.
