My strategy is removing duplicated data from array and show data just not duplicated.
const array1 = [{id:1 , name:"John" , age:20},
{id:2 , name:"Sam" , age:15},
{id:3 , name:"Paul" , age:28},
{id:4 , name:"David" , age:50},
{id:1 , name:"John" , age:20},
{id:4 , name:"David" , age:50}]
/*Expected result is
array1 = [{id:2 , name:"Sam" , age:15},
{id:3 , name:"Paul" , age:28]
*/Thank you.
