Render blocks of text if the value of the key is falsey. An inverted section syntax is similar to regular sections except it begins with a caret rather than a pound. If the value referenced is falsey, the section will render.
A key that references a value within the current or parent [can.stache.context context]. If the value is a function or can.compute, the function's return value is used.
Depending on the value's type, the following actions happen:
truthyvalue - the block is not rendered.
falseyvalue - the block is rendered.
The rendered result of the block or an empty string is returned.
