function parameters are returning undefined

I'm having a problem with my function syntax, when I call the function and give its two parameters strings the output is always undefined. I don't understand why its doing this, I was also wondering if this could go on the code review part of stack exchange since its bug free. Any answers would be greatly appreciated!

function sm(name, location){
  console.log("Hello " + this.name + " from " + this.location);
}

sm("josh", "hawaii");

You don't need to use this here. Just name and location is enough to refer the variable passed as the function parameter. 

function sm(name, location){
  console.log("Hello " + name + " from " + location);
}

sm("josh", "hawaii");

The function parameters are not properties of the function so you can't access them with this keyword.

And in your function this will refer to the global window object so the compiler will look for these properties inside the window object and will fire an exception if they weren't defined.

Just write:

console.log("Hello " + name + " from " + location);

Demo:

function sm(name, location){
  console.log("Hello " + name + " from " + location);
}

sm("josh", "hawaii");

No need using thisfor functional parameters.

function sm(name, location){
  console.log("Hello " + name + " from " + location);
}

sm("josh", "hawaii");
