The term "Function()" typically refers to a specific type of code block in programming that performs a particular task. Functions are reusable pieces of code that can take inputs, called parameters, and return outputs. They help organize code, making it easier to read and maintain. In many programming languages, such as Python, JavaScript, and Java, functions are defined using a specific syntax. By calling a function, a programmer can execute the code within it without rewriting the same instructions multiple times. This promotes efficiency and reduces the likelihood of errors in the code.
