why do i need to combine two objects into one?
pm.mixin = function(/*Object*/ obj, /*Object...*/ props){
if(!obj){ obj = {}; }
for(var i=1, l=arguments.length; i<l; i++){
mixin(obj, arguments[i]);
}
return obj; // Object
};
This a dojo mixin function http://docs.dojocampus.org/dojo/开发者_运维百科mixin#id2
Can anyone say me on what scenario this would be useful for me, why do i need to combine two objects into one. What is arguments.length, i don't even pass this...

- When subclassing
- When you want to override defaults as per the example you linked to in the question!
What is arguments.length
The arguments object contains the arguments passed to a function.
