Sort an array of numbers

This function sorts an array of numbers in ascending order.

JavaScript:

let sortNumbers = arr => [...arr].sort((a, b) => a - b);

// Example
console.log(sortNumbers([4, 2, 9, 3, 5, 1])); // [1, 2, 3, 4, 5, 9]
console.log(sortNumbers([10, -2, 4, -1, 5])); // [-2, -1, 4, 5, 10]

TypeScript:

let sortNumbers = (arr: number[]): number[] => [...arr].sort((a, b) => a - b);

// Example
console.log(sortNumbers([4, 2, 9, 3, 5, 1])); // [1, 2, 3, 4, 5, 9]
console.log(sortNumbers([10, -2, 4, -1, 5])); // [-2, -1, 4, 5, 10]
