Top-level await will allow us to simply runawait fetch(/* ... */)without all this boilerplate code.With a caveat: this only works in ES modules.For a single JavaScript file, without a bundler, you can save it with the .mjs extension and you can use top-level await....
The Array.from() method in JavaScript creates a new, shallow-copied instance of Array from an array-like or iterable object. You can use this method to convert array-like objects (objects with a length property and indexed items) as well as iterable objects (objects such as Map and Set)...

lib/State.js The state class will be the application state for our app. It extends the subject class, so in turn, it inherits all of the functions on the subject class. On instantiation, the constructor sets the state to an empty object. Theget()method just returns the state. Theupdate...
Another common method is to use thesplicemethod. Again,splicewill modify the original array, and works in much the same way. There is no real reason to use one over the other: letmyArr=["🍎","🍏","🍐","🍍"];myArr.splice(-1);console.log(myArr);// [ "🍎", "🍏", ...
