KnockoutJS: What Does Calling applyBindings Without Arguments do?

Getting into Magento 2’s KnockoutJS implementation, and being slightly annoyed at the JS world. Knockout’s a great framework, but by positioning themselves as an MVVM framework they create the impression that Knockout itself is enough to contain your entire application logic. Its not, and once developers adopt Knockout they end up building a custom, undocumented framework around it. Great for developers who want to keep themselves useful in a job – less great for creating an open source framework that anyone can learn to use and contribute to.
