What's the difference between run(...) & then(...)?

[matthewmueller]

I'm a little bit confused about the examples:
run(func1, func2).then(func3, func4).thenChain(func5, func6).thenRun(func7);

Isn't this just:
run(func1, func2).run(func3, func4).run(func5).run(func6).run(func7);

Are these methods just semantic sugar or do they have significant differences?

Hey Matthew, as the README says:

• then() is an alias for the previous method in the chain
• all methods have their own then alias - e.g. run() === thenRun()
• chain() is shorter way of writing run().then().then()

All of these are purely sugar and have a negligible overhead. When I made load.js, I thought the then() was more readable - just a matter of personal preference!

So yes, at the moment, the only 2 real unique methods are run() and defer() although I toyed with the idea of adding two more methods:

first(func1, func2, func3) - progress along the chain once any function completes

all(func1, func2, func3) - progress immediately after calling each function

I figured I'd let people make their own methods based on their needs.
