What is a program editor used for?

A program editor is specifically designed for creating and modifying programming code. It provides features that facilitate writing and organizing code, such as syntax highlighting, code completion, and error detection, which help programmers work more efficiently and reduce the likelihood of errors in their code. The primary focus of a program editor is on enhancing the coding experience, allowing developers to write, read, and debug their code more easily.

In contrast, editing images and videos pertains to different software tools, such as graphic design or video editing applications, which are not specialized for coding. While developing user interfaces involves a different set of tools and frameworks, a program editor may not directly handle the design aspect but could be used for coding the underlying logic. Running executable files falls under the realm of operating systems and runtime environments, where the code that has been edited and compiled is executed, rather than the focus of a program editor itself.
