If you don't mind using a library, I strongly suggest using the "ramda" library.

const arr = [ {key:"1",value:"dog"}
          , {key:"1",value:"dog"}
          , {key:"2",value:"cat"}
          , {key:"3",value:"bird"}
          , {key:"3",value:"bird"}
          ];
const result = R.uniq(arr);

result will be:

[{"key": "1", "value": "dog"}, {"key": "2", "value": "cat"}, {"key": "3", "value": "bird"}]

you can use "lodash" or other similar libraries too.
