Sort an array on an object property
npm install sort-onimport sortOn from 'sort-on';
// 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'}]Returns a new sorted version of the given array.
