Why imperative imports are slower than declarative imports

Why imperative imports are slower than declarative imports

A lot of people misunderstood Top-level await is a footgun, including me. I thought the primary danger was that people would be able to put things like AJAX requests in their top-level await expressions, and that this was terrible because await strongly encourages sequential operations even though a lot of the asynchronous activity we're talking about should actually happen concurrently.

But that's not the worst of it. Imperative module loading is intrinsically bad for app startup performance, in ways that are quite subtle.

Consider an app like this:

// main.js
'use strict';
const theGlobal = typeof window === 'object' ? window : global;
const realPromiseConstructor = theGlobal.Promise;
const wrappedPromiseConstructor = function (resolve, reject, progress) {
const originalPromiseInstance = new realPromiseConstructor(resolve, reject, progress);
// Who called us? Let's store it.

ES6 Currying Example
function add (x, y) {return x+y}
let curry = (f, ...args) => f.bind.apply(f,[null, ...args])
let add4 = curry(add,4)
console.log(add4(5)) //9
let add4n6 = curry(add4,6)
console.log(add4n6()) //10
// this is the react app. it knows nothing of the vanilla app, other than that the information
// will come in in props, and that it should call this hook when this button is pressed, or etc
var Spinner = (props) =>
<div>
{this.props.data}
<button value="↑" onclick={this.props.hooks.inc}/>
<button value="↓" onclick={this.props.hooks.dec}/>
</div>;
