I need to dynamically create array, knowing only how long I want it to be. So for example I need array to be 3 long so I need array = [-10, 0, 10], if I need array 9 long it will be [-40, -30, -20, -10, 0, 10, 20, 30, 40] etc. How can I do it automatically?
Another solution with Array.from:
const createArray = (length) => Array.from({length}, (el, i) => Math.round(i - length / 2) * 10);
console.log(createArray(1))
console.log(createArray(3))
console.log(createArray(9))Collected from the Internet
