Created March 13, 2020 01:04
The following code calculates a unit vector from coordinates (x, y) to the point (x1, y1).
const degrees = radians => radians * 180 / Math.PI;
const radians = degrees => degrees * Math.PI / 180;
function vecTo(x1, y1, x2, y2) {
const xDist = x2 - x1;
const yDist = y2 - y1;

} else if (xDist > 0 && yDist < 0) {
direction = 360 + degrees(Math.atan(yDist / xDist));

Keybindr - A small and easy way to bind callbacks to keys.
window.keybindr = (() => {

N8python / Fmait.js
Created June 23, 2019 11:01
An asynchronous, concurrent function for creating efficient, easy-to-understand promise pipelines.
async function fmait(callbacks, array) {
for (const callback of callbacks) {
array = await Promise.all(array.map(item => Promise.resolve(callback(item))));
}
return array;
