What is a Function?
Functions are specific objects that receive values, perform operations, and then return values. One of the most significant advantages of a function is its ability to be used multiple times, promoting code reusability.
Let's explore a simple function example:
In this example, the meeting
function is defined and takes a name
parameter. Inside the function is a code block containing various console.log
statements. The function is called three times with different names as arguments.
The power of functions lies in their reusability. This function, written in just 8 lines of code, contains a code block of 6 lines. However, it can be called multiple times, eliminating the need to copy and paste those 6 lines of code.
Note
The example here aims to provide a basic understanding of functions. No detailed analysis is needed for now. In practice, functions are versatile and help developers organize and reuse code effectively.
