I had a hard time reading the example until I applied the "normal" JS indentation, that would also likely be applied by Prettier and the likes. V(greeting, // initial value "hi" V(capitalize), // custom function call "Hi" V.concat("!"), // String method `concat` call "Hi!" V(send), // custom async function call Promise { <pending> } V.status, // automatic promise chaining + getting property Promise { 200 } V(console.log), // automatic promise chaining + global function call logs 200 ) It's certainly a nice usage of JavaScript's Proxy object and the resulting syntax is simple to grasp. Also glad to see the TS definitions in there. Well done!
