Why this Matters?

This question assesses the candidate's understanding of the fundamental programming paradigms in Dojo. Declarative programming focuses on describing what should happen, while imperative programming focuses on specifying how it should happen. A solid grasp of these concepts is crucial for effectively utilizing Dojo's declarative features and writing efficient code.

What to listen for?

Listen for the candidate's ability to clearly articulate the differences between declarative and imperative programming, including their advantages and use cases. Look for their understanding of how Dojo leverages both paradigms and their ability to provide examples or explain scenarios where each approach would be appropriate.

Why this Matters?

Asynchronous programming is a core aspect of web development, and handling asynchronous operations correctly is crucial for building responsive and efficient web applications. This question evaluates the candidate's familiarity with Dojo's mechanisms for managing asynchronous tasks and their ability to implement them effectively.

What to listen for?

Pay attention to the candidate's knowledge of Dojo's Promise-based API and their understanding of concepts such as deferreds, callbacks, and error handling. Look for their ability to explain how they would handle AJAX requests in Dojo, including making the request, handling responses, and managing any associated asynchronous dependencies.

Why this Matters?

Data binding allows for the automatic synchronization of data between different components in an application. Proficiency in implementing data binding is essential for building interactive and dynamic user interfaces in Dojo.

What to listen for?

Listen for the candidate's understanding of Dojo's data binding capabilities, such as the data store and the observable pattern. Look for their ability to explain how they would establish and maintain data binding relationships between components, and how they would handle updates and changes in the bound data.

Why this Matters?

Understanding the widget lifecycle and associated events is crucial for effectively managing the creation, rendering, and destruction of Dojo widgets. This question assesses the candidate's knowledge of Dojo's component lifecycle and their ability to work with widgets in a controlled manner.

What to listen for?

Pay attention to the candidate's familiarity with the different stages of the widget lifecycle, such as postCreate, startup, and destroy. Look for their understanding of the purpose and usage of important events, such as onLoad, onShow, onHide, and onDestroy. They should be able to explain how they would utilize these events and manage widget initialization and cleanup processes.
