Functions allow you to reuse code over and over. Our task is to make a simple `reusableFunction()` that prints out "Hi World" to the console (which you can reach with **Ctrl + Shift + I**).
|
||
|
|
||
|
You start off by using the `function` keyword, and then typing the function name (which follows Camel Case formatting). Then, type the `()`, and create the `{}` brackets. Like so:
|
||
|
|
||
|
```javascript
|
||
|
function reusableFunction() {}
|
||
|
```
|
||
|
|
||
|
Now, your function is ready to be typed in. Use the `console.log()` to print a message in the console. The basic code solution as follows:
|
||
|
|
||
|
```javascript
|
||
|
function reusableFunction() {
|
||
|
console.log("Hi World");
|
||
|
}
|
||
|
```
