JavaScript Function Default Parameters
New in the ES6 version of JavaScript are default function parameter values. This is something that has existed in other programming languages for quite a while but is new to JavaScript.
We can now create optional parameters for function arguments. We always had the ability to declare a long list of parameters in a function declaration and the function would run even when those parameters were not provided in the call to the function. The downside was that all the unprovided parameters had a value of undefined.
Now we can provide a default value for any parameter, which means that we truly have optional parameters for functions.
REMEMBER: always put your optional values at the end of your list. JavaScript won't know if you meant to skip over a value. The default values should be last and the required values should come first.
