what js file package order base on?

[lusess123]

in vs2013, we set Combine Javascript output into file ,
my question is: what each js file order base on ?

[DanielRosenwasser]

My understanding is that your tsconfig.json or your file list in your project file will be processed in that order. If any of your files have a /// <reference path="..." /> and the referenced file has not already been specified, then those referenced files will be concatenated before the contents of the current file.

Correct. One last alternative is including a file named _references.ts in the root of your project directly with the set of /// references you want in a particular order.

@lusess123 you might find my comment in #1066 (comment) has some more information; specifically the "Ordering output with --out" section.
