AppBuilder action

Could we use AppBuilder action from different AppBuilder application or service?

Adobe AppBuilder action in Adobe I/O runtime namespace is internal only, and could be use within the namespace until we expose them as a web-action. Once an Adobe I/O runtime action become web-action then, other users could use that from outside the namespaces just like an web service or internal action.

Why do we have computer programming?

Computer programming exists because computers can only understand and execute instructions that are given to them in a specific language or format. Programming allows humans to create these instructions or code, which can be executed by computers to perform a wide range of tasks and automate processes.

Programming is essential because it allows humans to communicate with computers in a way that they can understand and perform complex operations. Without programming, computers would not be able to perform the tasks that they do today, such as running software applications, processing data, and powering the internet.

In addition, programming enables humans to create new technologies, innovate, and solve complex problems in a variety of fields, including science, engineering, medicine, and finance. It has also become an important skill for the modern workforce, as more and more jobs require knowledge of programming and software development.

Overall, computer programming is a crucial aspect of modern technology and has enabled humans to achieve incredible feats in terms of computation, automation, and innovation.

Hope this help you to understand the basic need of computer programming.
