Using coding standards in development is significant because it fosters consistency, readability, and maintainability in code. Standards ensure that all team members adhere to a common set of rules, making it easier for developers to understand each other's work and collaborate effectively. This practice reduces the likelihood of coding errors and enhances the quality of the software. Furthermore, adhering to coding standards can facilitate smoother code reviews and assist in the onboarding of new team members by providing a clear framework for writing and organizing code.
