// four(plus(nine())); // returns 13
// eight(minus(three())); // returns 5
// six(dividedBy(two())); // returns 3

JS snippet for increasing or decreasing font size in a HTML document using jQuery.
function resize(increase_or_decrease) {
const direction = increase_or_decrease;
// First arg is the direction, elements to change follow
for (let i = 1; i < arguments.length; i++) {
let fontsize = parseInt($(arguments[i]).css('font-size'));
if (direction === 'increase') {
fontsize++;
if (fontsize > 20) fontsize = 20; // Prevent text from getting too big
} else if (direction === 'decrease') {
fontsize--;

vat.py tells you what's the applicable VAT in the country of your choice. I wrote this one because at a previous workplace I had to check VAT in various countries quite often – but not often enough to memorize all.
