What is new in the ES2021 edition of “JavaScript for impatient programmers”?

Free to read online: exploringjs.com/impatient-js/

• The exercises now run as native ESM modules on Node.js. Previously, they were run via the esm package.
• Material on new ES2021 features:
  • String.prototype.replaceAll()
  • Promise.any()
  • Logical assignment operators
• Underscores (_) as separators in number literals and bigint literals

Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Setup Traefik 2.2 with Let's Encrypt On LKE

If you searched for this article I chances are you know what LKE, Traefik and Let's Encrypt are, else here is a quick primer:

What is LKE?

"The Linode Kubernetes Engine (LKE) is a fully-managed container orchestration engine for deploying and managing containerized applications and workloads.". For more information please have a look at "Deploy and manage a cluster with Linode Kubernetes Engine"

systemd Service Unit for Traefik

Adapted from caddy systemd Service Unit

The provided file should work with systemd version 219 or later. It might work with earlier versions. The easiest way to check your systemd version is to run systemctl --version.

Instructions

We will assume the following:

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

In this article I will take a very simplistic approach in understanding memory leaks and I will also attempt to diagnose them.

In todays world of abundant memory, we seldom worry about memory leakages. But I hate to tell you that we live in a real world and nothing comes for free.

Oh my fancy functional programming

Disclosure: I absolutely love functional programming. Functional programming is cool and with the new ES6 syntax it becomes even cooler.

Thanks [David Simmons][david-simmons] for this awesome article!

[Tokio][tokio] 是 Rust 的開發框架，用於開發非同步 I/O 程式（asynchronous I/O，一種事件驅動的作法，可實現比傳統同步 I/O 更好的延伸性、效能與資源利用）。可惜的是，Tokio 過於精密的抽象設計，招致難以學習的惡名。即使我讀完教程後，依然不認為自己充分內化這些抽象層，以便推斷實際發生的事情。
