Remove same Id or duplicate data from array

 let arrayFlat = [

{id:25 , name:"jaypal"},

{id:25 , name:"jaypal"},

{id:26 , name:"hello"},

{id:27 , name:"hi"}

]

 const output = [...new Map(arrayFlat.map(o => [o.id, o])).values()]

expected output:  let arrayFlat = [

{id:25 , name:"parmar"},

{id:26 , name:"hello"},

{id:27 , name:"hi"}

]
