// Sort by an object property sortOn([{x: 'b'}, {x: 'a'}, {x: 'c'}], 'x'); //=> [{x: 'a'}, {x: 'b'}, {x: 'c'}]

// Sort descending by an object property sortOn([{x: 'b'}, {x: 'a'}, {x: 'c'}], '-x'); //=> [{x: 'c'}, {x: 'b'}, {x: 'a'}]

// Sort by a nested object property sortOn([{x: {y: 'b'}}, {x: {y: 'a'}}], 'x.y'); //=> [{x: {y: 'a'}}, {x: {y: 'b'}}]

// Sort descending by a nested object property sortOn([{x: {y: 'b'}}, {x: {y: 'a'}}], '-x.y'); //=> [{x: {y: 'b'}, {x: {y: 'a'}}}]

// Sort by the x property, then y sortOn([{x: 'c', y: 'c'}, {x: 'b', y: 'a'}, {x: 'b', y: 'b'}], ['x', 'y']); //=> [{x: 'b', y: 'a'}, {x: 'b', y: 'b'}, {x: 'c', y: 'c'}]

// Sort by the returned value sortOn([{x: 'b'}, {x: 'a'}, {x: 'c'}], element => element.x); //=> [{x: 'a'}, {x: 'b'}, {x: 'c'}] ```
