[removed] get subarray from an array by indexes

Question

Is there a one-line code to get an subarray from an array by index?

For example, suppose I want to get [\"a\",\"c\",\"e\"] from [\"a\",\"b\",\"c\"

Answer 1

You can use Array.prototype.reduce()

const arr = ['a', 'b', 'c', 'd', 'e'];
const indexes = [0, 2, 4];

const result = indexes.reduce((a, b)=> {
a.push(arr[b]);
return a;
}, []);

console.log(result);
