To remove Random object we need Index Number of that object -  //here Vasu is array name - var index = vasu . findIndex ( x => x . _id === "1" ); // find Index by Property & its value       console . log ( index )       if ( index >= 0 ) {         vasu . splice ( index , 1 ); //1st parameter is Index number & 2nd is Remove count       }
