在 object 数组中找到最低和最高

Question

I need to find 4 values in this order in a array of object:

• lowest x & y

• highest x and lowest y

• highest x & y

• highest y & lowest x

my object is like this:

   object: [
            {id: 1, x: 160, y: 160},
            {id: 2, x: 192, y: 160},
            {id: 3, x: 224, y: 160},
            {id: 4, x: 224, y: 192},
            {id: 5, x: 192, y: 192},
            {id: 6, x: 160, y: 192},
            {id: 7, x: 160, y: 224},
            {id: 8, x: 192, y: 224},
            {id: 9, x: 224, y: 224}
           ],

the result must be an array with those 4 object.

Thanks

This is not the complete answer; highest x and lowest y and vice versa remained but it might give other contributors some insights how to solve the problem:

 const object = [ {id: 9, x: 224, y: 224}, {id: 2, x: 192, y: 160}, {id: 3, x: 224, y: 160}, {id: 4, x: 224, y: 192}, {id: 5, x: 192, y: 192}, {id: 6, x: 160, y: 192}, {id: 7, x: 160, y: 224}, {id: 8, x: 192, y: 224}, {id: 1, x: 160, y: 160}, {id: 9, x: 224, y: 224} ]; object.sort((objA, objB) => (objA.x * objA.y) - (objB.x * objB.y)); const HighestXAndHighestY = object[object.length-1]; const lowestXAndlowestY = object[0]; console.log(HighestXAndHighestY) console.log(lowestXAndlowestY)
