JavaScript version
const sortBy = (arr, k) => arr.concat().sort((a, b) => (a[k] > b[k] ? 1 : a[k] < b[k] ? -1 : 0));
TypeScript version
const sortBy = <T extends Record<string, any>, K extends keyof T>(arr: T[], k: K): T[] => (
arr.concat().sort((a, b) => (a[k] > b[k] ? 1 : a[k] < b[k] ? -1 : 0))
);
Example
const people = [
{ name: 'Foo', age: 42 },
{ name: 'Bar', age: 24 },
{ name: 'Fuzz', age: 36 },
{ name: 'Baz', age: 32 },
];
sortBy(people, 'age');
// [
// { name: 'Bar', age: 24 },
// { name: 'Baz', age: 32 },
// { name: 'Fuzz', age: 36 },
// { name: 'Foo', age: 42 },
// ]
