I’ve array of objects and i need to update the document if it’s exist in the array or push it if it’s not.

ex:

I have this array: [

{key: 1, name: ‘s’},

{key: 2, name: ‘n’},

{key: 3, name: ‘r’}

]

db collection documents:

[

{key: 1, name: ‘s’}, {key: 2, name: ‘t’}

]

i need the result to be like this in collection:

[

{key: 1, name: ‘s’}, {key: 2, name: ‘n’}, {key: 3, name: ‘r’}

]
