passedin

passedin refers to a concept in programming where a value is transmitted from one part of a program to another, typically between functions or methods. This is commonly achieved through arguments or parameters. When a function is called, certain values can be provided to it, which the function then uses in its operations. These provided values are known as arguments, and the variables within the function definition that receive these values are called parameters.

The mechanism of passing values allows for code reusability and modularity. Instead of writing the same logic multiple times, a function can be created with parameters that accept different inputs, enabling it to perform its task with varying data. This promotes a more organized and maintainable codebase.

There are different ways values can be passed, the most common being pass-by-value and pass-by-reference. In pass-by-value, a copy of the argument's value is passed to the function. Any modifications made to the parameter within the function do not affect the original argument outside the function. In contrast, pass-by-reference passes a reference or memory address to the argument. Changes made to the parameter within the function directly alter the original argument. The specific implementation of passedin behavior can vary across different programming languages.
