Homonym: Placeholder (Token)
A "placeholder" is a term used to describe a symbol or text that temporarily represents something else. For example, in a document, you might see a blank space or a word like "TBD" (to be determined) where information is yet to be filled in. This helps keep the structure of the document intact while waiting for the final details.
In programming, placeholders are often used in code to indicate where a value will be inserted later. For instance, in a function, you might see a placeholder like variable that will be replaced with actual data when the program runs. This makes it easier to organize and manage code efficiently.
