Built in functions additional syntax

I noticed when using emmet in VSCode, the adjust-hue or map-get functions, it automatically creates something almost like key value pairs for arguments. Here is an example:

@for $i from 1 to 10 {
  .box-#{$i} {
    background-color: adjust-hue(tomato, $i *20);
    // can also be written as
    background-color: adjust-hue($color: tomato, $degrees: $i * 20);

This obviously isn't necessary to get the same output that Guil Hernandez gets, but is this technically the correct syntax for these built in functions?

The adjust-hue() function expects the $color and $degrees arguments to be input in the correct order, as Guil does in the video. If you use the keys the values can be input in any order. VSCode throws them up automatically for you because it's nice like that. So, you don't need to use them, if you remember to arrange your arguments in the right order.
