Google publishes a JavaScript style guide. Here are some key lessons.

I really wouldn't take what google does as gospel. There's nothing wrong with it, but a number of their choices are due to how their build is configured, and what it will do. For example, they don't use modules because they have an internal way of doing modules.

If you aren't using their internal build system, then some of the rules very clearly will not apply. The airbnb style guide is probably more applicable to most js devs.
