`
npm i oa2o

oa2o(ar, key[, valKey])
- ar = (array) object array ( [{k:"a"}, {k:"b"}] )
- key = (string) key in object array; the value of this specified key will be used as the key for new object; usually choose key with unique value.
- valKey = (string|array) key in object array; the value of this specified key will be used as the value for the key in new object, instead of the whole original object element.
##### return
return object
Return object with shallow copy.
