Calling a Function

To call a function, we need to use the function's name, followed by parentheses (). The parentheses are essential, as they indicate to the programming language that we want to execute the function.

Example:

1// Define a function that prints a greeting message
2function greet() {
3  console.log('Hello, welcome!');
4}
5
6// Call the greet function
7greet();

In the example above, we have defined a function greet() that prints a greeting message. By calling the greet() function, we execute the code within the function, and the message "Hello, welcome!" will be displayed in the console.
