Assert that an object contains certain properties. This is a convenient way to assert, for example, that certain parameters or options have been provided. By default, all specified properties must be defined (an "and" check), but it is also possible to specify that a certain number of the possibilities are defined (an "or" check). An equivalent PHP package, @aponica/assert-properies-php, is available, and should be kept synchronized with this version for consistency.
