This Meteor smart package provides a reactive lookup of a field in the object.
It matches the behavior of the lookup in Spacebars, so {{foo.bar}} resolves
the same as DataLookup.get(dataContext, 'foo.bar').
Adding this package to your Meteor application adds DataLookup class
into the global scope.
Both client and server side.
or add peerlibrary:data-lookup
DataLookup provides the following static methods:
lookup(obj, path) ? resolves the value by traversing the obj object using the path; if path is
a string, it is first split on .; if a value is not found, undefined is returned; if any value on
path is a function, it is first calledget(obj, path, equalsFunc) - same as lookup, but if called inside a reactive computation, it uses
ComputedField to minimize invalidations so that the
reactive computation is invalided only when the value looked up itself changes, and not every time the input object
changes; you can use equalsFunc to use a different equality function to determine when the value has changed
