Helpful article. How would you remove objects that are duplicates in just one value

[

{id:0,key1:'hello', key2:'there'}

{id:1,key1:'hello', key2:'buddy'}

{id:2,key1:'hello', key2:'friend'}

{id:3,key1:'Bye', key2:'buddy'}

{id:4,key1:'Bye', key2:'friend'}

]

to give,

[

{id:0,key1:'hello', key2:'there'}

{id:3,key1:'Bye', key2:'buddy'}

]

or [

{id:0,key1:'hello'}

{id:3,key1:'Bye'}

]

Basically it's the hello and Bye that are important
