As they say, “two heads are better than one“.
Pair programming is a technique used by software development teams. It is strongly encouraged by Extreme Programming (XP) methodology. Two programmers work together at one computer, with one person typing and the other person reviewing the code as it is being written. Then, they exchange the role. They discuss the issue and come to conclusions together. The goal of pair programming is to improve the quality of the code and to catch mistakes early on, by having two people review the code as it is being written. Additionally, it helps promote knowledge sharing and communication among team members, who also develop stronger relationships and trust.
Example: You use second brain even if you are not a programmer! If you encounter an issue, you ask other people for their thoughts, often quickly tackling the problem together.
