What is function call?

You call the function by typing its name and putting a value in parentheses. This value is sent to the function’s parameter.

e.g.

var firstFunction = function(firstParameter)
{
console.log("Print the " + firstParameter;
}
firstFunction("string as it's shown.");

In this example the function’s name is firstFunction The parameter’s name is firstParameter

We call the function firstFunction(“string as it’s shown.”);

This sends the string “string as it’s shown.” to the function and the parameter firstParameter takes it’s value.

Now the code inside the function actual reads

“Print the “ + “string as it’s shown.”;

Does that make sense?
