Rust = Future<C++>

In this channel I introduce Rust for people who know C++ already. The videos are supposed to be short and cover only a single topic. Each video comes with a github gist, which contains all the code and commands for copy/paste, such that you can easily try out things. Furthermore, there are links to the excellent Rust documentation.

This is still work in progress. As you can see in the table below,

    key: Option<K>,
    value: Option<V>,
    left: Option<Box<BST<K, V>>>,
    right: Option<Box<BST<K, V>>>,
}

impl<K: Ord + Clone, V: Ord + Clone> BST<K, V> {
    fn init() -> Box<BST<K, V>> {
        return Box::new(BST::<K, V> {

// - show release notes
// - send telemetry
// - recommend things

// This disables all of that stuff.

You are doing JSON APIs wrong.

When you use JSON to call an API - not a REST API, but something like JSON-RPC - you will usually want to encode one of several possible messages.

Your request body looks like this:

ES Modules are terrible, actually

This post was adapted from an earlier Twitter thread.

It's incredible how many collective developer hours have been wasted on pushing through the turd that is ES Modules (often mistakenly called "ES6 Modules"). Causing a big ecosystem divide and massive tooling support issues, for... well, no reason, really. There are no actual advantages to it. At all.

It looks shiny and new and some libraries use it in their documentation without any explanation, so people assume that it's the new thing that must be used. And then I end up having to explain to them why, unlike CommonJS, it doesn't actually work everywhere yet, and may never do so. For example, you can't import ESM modules from a CommonJS file! (Update: I've released a module that works around this issue.)

And then there's Rollup, which apparently requires ESM to be u
