{{alias}}( arr, prop[, options] )
Extracts a property value from each element of an object array.
The function skips `null` and `undefined` array elements.
Extracted values are not cloned.
Parameters
----------
arr: Array
Source array.
prop: string
Property to access.
options: Object (optional)
Options.
options.copy: boolean (optional)
Boolean indicating whether to return a new data structure. To mutate the
input data structure (e.g., when input values can be discarded or when
optimizing memory usage), set the `copy` option to `false`. Default:
true.
Returns
-------
out: Array
Destination array.
Examples
--------
> var arr = [
... { 'a': 1, 'b': 2 },
... { 'a': 0.5, 'b': 3 }
... ];
> var out = {{alias}}( arr, 'a' )
[ 1, 0.5 ]
> arr = [
... { 'a': 1, 'b': 2 },
... { 'a': 0.5, 'b': 3 }
... ];
> out = {{alias}}( arr, 'a', { 'copy': false } )
[ 1, 0.5 ]
> var bool = ( arr[ 0 ] === out[ 0 ] )
true
