In this JavaScript tutorial we begin to look at Function Declarations. In Codecademy's JavaScript course, Function section, we learn about function declarations. We learn that all functions begin with the function keyword. Right after the function keyword is the function name, also called the function identifier. After the identifier, we have the function body which has the code we will be running when the function is called. We learn how to write a function in this lesson, but we do not learn how to call it, though we did see an example of it when hoisting was explained to us. We will learn more about calling functions in the next lessons, but for now, make sure you understand how to declare a function in JavaScript. Understanding function declarations in programming is a huge leap forward into the world of professional development.
