In this lesson, we take a look at Calling a Function in JavaScript Programming, Codecademy’s JavaScript Functions Section. This is a JS Guide that explains how to call a function. In our previous lesson we looked at JavaScript function declarations but did not cover how to use, or call, the function we declare. We learn that we are able to declare a function using the function keyword. We then give our function a name, also called an identifier, which is followed by parentheses. Curly braces then follow and the code we want to execute is between our curly braces. We then learn that we can call our function by simply using its identifier followed by parentheses. This will call our function and will run all the code within curly braces. Understanding this is huge in your JavaScript programming journey and make sure to understand calling a function in 2023 and beyond forever!

When it comes to JavaScript programming, knowing how to call a function is a fundamental concept that every developer should master. In this JavaScript tutorial, we will explore how to call a function in Codecademy’s JavaScript Functions Section. This comprehensive JS guide will help you understand the ins and outs of calling functions in JavaScript.

In the previous lesson, we learned about JavaScript function declarations, which taught us how to define a function. Now, we will take a closer look at how to use the function we declared by calling it. To call a function, we simply need to use its identifier, which is the function name, followed by parentheses. The parentheses can contain any arguments that we want to pass into the function.

By calling a function, we can execute the code within the function body. This is useful because we can reuse the same code multiple times without having to repeat it in our program. We can also pass different arguments into the function each time we call it, which allows for even more flexibility in our programs.

To better understand how to call a function, let’s take a closer look at the syntax. First, we declare our function using the function keyword, followed by the function name and parentheses. Inside the parentheses, we can specify any parameters that the function will accept. Then, we define the function body using curly braces. Within the function body, we can execute any code that we want the function to perform.

Once we have defined our function, we can call it by using its identifier, followed by parentheses. Inside the parentheses, we can specify any arguments that we want to pass into the function. When the function is called, it will execute the code within its body, using the arguments we passed in (if any).

Understanding how to call a function is crucial in becoming a proficient JavaScript developer. With the help of Codecademy’s JavaScript Functions Section, you will learn how to create and call functions with ease. This knowledge is essential for anyone looking to take their programming skills to the next level.

In summary, calling a function in JavaScript is a critical concept that every developer should understand. By mastering this fundamental concept, you will be well on your way to becoming a proficient JavaScript programmer. With Codecademy’s JavaScript Functions Section, you can learn everything you need to know about creating and calling functions in JavaScript. So, dive in and start your journey to becoming a master of JavaScript programming!
