Description: The ‘default value’ refers to a value that is automatically assigned to a variable or parameter in programming if no explicit value is provided. This concept is fundamental in modern programming languages, as it allows developers to define initial behaviors and configurations without needing to specify a value each time. Default values are particularly useful in various contexts, including functions, methods, and classes, where initial values can be set for parameters and properties. This not only simplifies the code but also enhances readability and maintainability, as developers can rely on certain variables having a known value instead of having to manage cases where they are not assigned a value. Additionally, using default values can help prevent common errors, such as accessing undefined variables, contributing to a smoother and more efficient development experience.
