What feature of the active context allows for immediate validation of source code?

The feature that allows for immediate validation of source code in an active context is local validation as you type. This capability enables a developer to receive instant feedback as they write their code, allowing for real-time error detection and correction. As the developer types, the IDE analyzes the syntax and structure of the code, highlighting any errors or discrepancies. This not only improves efficiency but also enhances the coding experience by reducing the need for extensive debugging sessions later on.

Local validation as you type is crucial in environments like the Avaloq Integrated Customization Environment, as it supports a more interactive and fluid coding process. It empowers developers to maintain code quality and adhere to best practices without interrupting their workflow to perform separate validation steps or waiting for a full compile and test cycle.
