Created January 5, 2011 21:36
A minimal jQuery-based JavaScript UI framework. In-progress and a bit raw.
(function(){ // begin private function
var copyProperties = function(props, o, overwrite, wrapFunctions) {
var wrap = wrapFunctions ? wrapFunctionWithSelf : nowrapFunction;
if (props) {
for (key in props) if (overwrite || o[key] === undefined) {
var getter = props.__lookupGetter__(key);
var setter = props.__lookupSetter__(key);

Created October 16, 2013 19:30
Code to reproduce an issue where Vert.x's `HttpClient.connectWebSocket()` hangs indefinitely and never calls the exception handler, if the connection is terminated during WebSocket connection negotiation.
HttpClient httpClient = vertx.createHttpClient();
httpClient.setHost("localhost");
httpClient.setPort(8888);
httpClient.setConnectTimeout(1000); // 1 second
httpClient.exceptionHandler(new Handler<Throwable>() {
@Override
public void handle(Throwable event) {
System.out.println("Failed!"); // never called
}
});

nfarina / useResettableState.ts
Created August 6, 2021 16:24
A version of React's `useState` that resets the value to initial whenever the given dependency array changes. Very helpful when you need to reset some internal state as the result of getting new props.
import { DependencyList, Dispatch, SetStateAction, useState } from "react";
/**
* This is like useState() but with the added feature of returning the initial
* value whenever the dependency list changes. This is super useful for allowing
* components to "reset" some internal state as a result of getting new props.
*/
export function useResettableState<S>(
initial: S | (() => S),
deps: DependencyList,
