first else $val == none cannot work without if, second the no border is confusing. if you have some lint or go to w3 you find out the parameter is just none.

@mixin border-stroke($val){
@if $val == light{
border-stroke:1px solid black;
}
@else if $val == medium {
border:3px solid black;
}
@else if $val == heavy{
border:6px solid black;
}
@else {
border:none;
}
}

Hope it is helpful for U
