What is a key feature of frameworks used in programming?

A key feature of programming frameworks is that they offer a structured set of conventions and predefined tasks that help streamline the development process. By utilizing a framework, developers can focus more on the unique aspects of their application rather than getting bogged down by repetitive or boilerplate code. This often leads to increased productivity, more consistent coding practices, and enhanced collaboration among team members. Frameworks can include libraries, templates, and a variety of tools that collectively support the developer throughout the various stages of application design and implementation.

In contrast, the other options do not accurately reflect the fundamental purposes of frameworks. Extensive manual coding is often minimized because frameworks are designed to reduce redundant coding efforts. While some frameworks may include user interface elements, their scope typically extends far beyond just UI, encompassing a wide range of functionalities. Lastly, frameworks do not inherently limit programming language options; many are built to work with multiple languages or provide flexibility in integration.
