This is how to use jsdom repetitively without leaking memory
const jsdom = require('jsdom');
const domBuilder = (iter) => {
new jsdom.JSDOM(`${iter}`);
if (iter % 1000 === 0) {
console.log(iter); // eslint-disable-line no-console
}
setImmediate(domBuilder.bind(null, iter + 1));

Memory leak in JSDOM...???
const jsdom = require('jsdom');
for (let iter = 0; ; iter += 1) {
new jsdom.JSDOM(`${iter}`);
if (iter % 1000 === 0) {
console.log(iter); // eslint-disable-line no-console
}
}

Generate TSV file from JMDict XML data
const fs = require('fs');
function getEntryStrings() {
const ret = [];
const text = fs.readFileSync('JMdict_e').toString();
const openPos = [];
const endPos = [];

Bug in rasterizer? Try it with Chrome running on Windows with high-DPI (screen scaling).

Let's play with window.postMessage()
<!doctype html>
<html lang="en">
<meta charset="UTF-8">
<title>Master</title>
<script>
window.addEventListener('DOMContentLoaded', function () {
document.querySelector('#triggerBtn').addEventListener('click', function () {
const slaveWindow = window.open('slave.html');

Let's learn about open(2) (called by fopen(3))
#include <stdio.h>
#include <unistd.h>
#define TEST_TXT "test.txt"
void phase1(void) {
FILE * fp = fopen(TEST_TXT, "w");
fprintf(fp, "hoge\n");
fclose(fp);
