javascript - How can I get the smallest two numbers from an array in js?

Question

Hey I've been trying to return the 2 smallest numbers from an array, regardless of the index. Can you please help me out?

Answer 1

• Sort the array in the ascending order.
• Use Array#slice to get the first two elements (the smallest ones).

var arr = [5, 4, 7, 2, 10, 1],
    res = arr.sort((a,b) => a - b).slice(0, 2);
    console.log(res);
