Calling Functions

In our last code example we created a function, but as you may have checked, it did not produce any output. Why? Because functions need to be invoked by a call to use them in a program. Calling a function means to specify the function name of the function that we want to use in the program. This executes all the statements present inside the function.

Consider the same example as in previous section. Now we specify a statement which denotes the function name along with the parenthesis, after the function implementation. This statement invokes the call to the function. The code block below demonstrates this behavior.

function js_func(){

    console.log("Hello World!")

}
