Defining a function without calling it is indeed possible in JavaScript and many other programming languages. When you write a function definition, you create a reusable block of code but do not execute it until you explicitly call it later in your program. This allows for modular programming, where functions can be defined in one part of your code and invoked from another, enhancing code organization and reusability.

For example, you can define a simple function like this:


function greet() {

console.log("Hello, World!");

}

At this point, the function greet is defined but not called, meaning no output will occur until you invoke the function using greet();. This capability is fundamental to programming, as it allows developers to structure their code effectively without immediately executing every piece of logic upon definition.

Other options may suggest limitations or conditions on function definitions, which do not accurately reflect the core behavior of function handling in most programming environments.
