Why is pair programming beneficial during training?

Pair programming is beneficial during training primarily because it promotes collaboration and knowledge sharing. In a pair programming environment, two programmers work together at one workstation, with one person writing code (the "driver") while the other reviews each line of code and offers suggestions (the "observer" or "navigator"). This collaborative approach allows both individuals to engage in active learning, facilitating immediate feedback and discussion about different coding approaches, tools, and techniques.

Moreover, it encourages the sharing of knowledge and skills between participants. A more experienced programmer can guide a less experienced peer, helping to bridge knowledge gaps and enhance understanding. This mutual learning enhances problem-solving abilities and fosters a deeper comprehension of coding practices, which is crucial for effective software development. As a result, this collaborative learning environment helps reinforce concepts and develop better coding habits through continual interaction and discussion of best practices.

Other choices suggest isolation or a focus on individual skills, which diminish the benefits of learning through collaboration that pair programming inherently provides. Thus, the collaborative nature of pair programming is what makes it particularly advantageous during training.
