Primitive Types & Reference Types in JavaScript

Primitive Types & Reference Types in JavaScript

An explanation of JavaScript's pass-by-value, which is unlike pass-by-reference from other languages.

Facts

  • JavaScript has 2 kinds of variable types: primitive and reference.
  • A fixed amount of memory is reserved after creation of every variable.
  • When a variable is copied, it's in-memory value is copied.
  • Passing a variable to a function via a call also creates a copy of that variable.

This gist shows how to use an <svg> element as an icon-image for a Mapbox GL symbol layer
// How to add an SVG as a symbol layer's icon image: https://github.com/mapbox/mapbox-gl-js/issues/5529#issuecomment-340011876
// Also see here: https://stackoverflow.com/a/11765731/2748013 (we need the data url stuff for the image src)
// NOTE: Importing SVGs requires an inline module loader such as https://github.com/webpack-contrib/svg-inline-loader
import template from './templates/marker.svg';
const width = 20;
const height = 40;
const img = new Image(width, height);
// map is your Mapbox GL map object

    • Who is going to use it?
    • How are they going to use it?

WireGuard over TCP with udptunnel

WireGuard over TCP with udptunnel

udptunnel is a small program which can tunnel UDP packets bi-directionally over a TCP connection. Its primary purpose (and original motivation) is to allow multi-media conferences to traverse a firewall which allows only outgoing TCP connections.

知识星球原生视频组件，无法通过键盘操作前进、后退、暂停、播放，于是写了一个简单的脚本，要先安装好篡改猴Tampermonkey等插件管理器。然后新建脚本，并复制如下代码
