This function is deprecated, but will not be removed in the 1.x lifecycle. There are edge cases (see known issues) that are not supported by this function. We suggest using another, similar library for all-purpose merging, such as lodash's merge().
Deeply extends the destination object dst by copying own enumerable properties from the src object(s)
to dst. You can specify multiple src objects. If you want to preserve original objects, you can do so
by passing an empty object as the target: var object = angular.merge({}, object1, object2).
Unlike extend(), merge() recursively descends into object properties of source
objects, performing a deep copy.
This is a list of (known) object types that are not handled correctly by this function:
BlobMediaStreamCanvasGradientangular.merge also does not support merging objects with circular references.
