Why Senior Developers Google Basic Syntax
Senior developers often Google basic syntax not due to a lack of knowledge, but because they focus on strategic thinking and problem-solving rather than memorizing specific syntax. This approach helps manage cognitive load, allowing them to utilize external resources efficiently. The skill of efficiently finding information is a hallmark of seniority. Teaching juniors to embrace Googling as a normal practice can help reduce imposter syndrome and highlight that expertise lies in judgment and application of concepts.
