Description

Creates a deep copy of source, which should be an object or an array.

If no destination is supplied, a copy of the object or array is created.
If a destination is provided, all of its elements (for array) or properties (for objects) are deleted and then all elements/properties from the source are copied to it.
If source is not an object or array, source is returned.

Note: this function is used to augment the Object type in Angular expressions. See ng.$filter for more information about Angular arrays.

Usage

angular.copy(source[, destination]);
