[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 filter

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

const result = arr.filter((elt, i) => indexes.indexOf(i) > -1);

document.body.innerHTML = result;
