Comparing two strings with special characters via charCodeAt
A string is a sequence of bytes. As such, it cannot be rendered as anything except as bit pattern. Next, a character set comes into play. Here, you map numbers to characters, for example 65 to A, 97 to a and 228 to ä. Finally, you need a character encoding, which maps the number to a bit pattern. For number 228, the usual 8-bit encoding simply uses 0xE4 as bit pattern. UTF-8 encoding will use 0xC3 0xA4 as bit pattern and UTF-16 will use 0x00 0xE4 as bit pattern. So in order to properly compare a string, you need to know its bit pattern (byte sequence), its encoding and its character set. If you lack any, strings cannot be properly compared. Nowadays, Unicode is used as character set most of the time. If you only use the very basic characters, ASCII will do the job as well. ASCII is a s

What is ByteArrayEntity and equivalent in JavaScript
Probably the byte array is base 64 encoded. You can prefix it like this on your server and the browser will see it as image data. data:image/jpeg;base64,BBBBBB... Where BBBBBB... is your byte array

Equivalent of $(this) in native javascript
Within the event handler this will represent the element to which the event handler is bound. You will not have all of the utility functions provided by jQuery. So in your example you will not be able to retrieve the data attribute by using this.data("something") To retrieve the value of the custom attribute the code must pass the event to the function. From the event or e in the example, the target property will contain the element that triggered the event, which may not always be the element to which the event handler was bound, due to the propagation of events. Use the getAttribute method to retrieve the value of custom attribute. Also refrain from making the custom attributes upper case as the html specifications do not allow for this and will create inaccessible attributes. var

Equivalent of JavaScript in TypeScript
Durandal expects an instance of the object to be returned from the module. Typescript's AMD convention is export constructor. Discussion about this problem and plugin solution here: https://github.com/BlueSpire/Durandal/pull/244 I've created Durandal v2.0 plugin to help solve the problem: https://gist.github.com/Jaben/6180861 It will find the exported class for the view and use that if it's available. You will also need to mark the "shell" class as export in TypeScript: import _config = require('config'); import _router = require('plugins/router'); import _app = require('durandal/app'); export class shell { //.... }

JavaScript AddedToStage equivalent
If you're using a function such as appendChild to add static text to the DOM, that's a synchronous event. It will be added and rendered by the time your function returns. If you're appending a child that depends on an external resource, you're looking for the onload event. This works for the main document (window.onload = function() { ... }), and according to Can you put the JavaScript onload event anywhere besides in the body tag?, body, frame, frameset, iframe, img, link and script. (They apparently get their information from http://www.w3schools.com/jsref/event_onload.asp, which is not nearly as good as straight from the spec, but I couldn't find the details in there.)

What is the equivalent of Java's final in javascript
If setOnclick is implemented nicely, you should probably be able to do: bt.setOnclick(function() { alert(this.name + " clicks = " + this.cntClick); this.onclick = this.cntClick + 1; }); Otherwise, you need to create a new scope for each callback function so that they each have their own bt. One way to do that would be: bt.setOnclick(function(bt){ return function(){ alert(bt.name + " clicks = " + bt.cntClick); bt.onclick = bt.cntClick + 1; }; }(bt)); Comment Response To implement setOnClick such that this refers to the relevant HrButton (rather than the element) within the callback, you can use the following code (works in modern browsers only, unless you SHIM bind): var self = this; self.setOnClick = function(fnOnClick) { element.onclick = fnOnCl

No, but you could write your own like: var Preconditions = { checkArgument: function(condition, message) { if (!condition) { throw Error('IllegalArgumentException: ' + (message || '')); } } } and in your business logic function getPublishedPort(port) { Preconditions.checkArgument(port.isPublishedPort(), 'Given port is not a published port.'); // ... Business logic ... } Though I guess it can't do formatting with lazy evaluation for you.

Equivalent of a class loader in Javascript
RequireJS does exactly this by allowing you to define your dependencies and then only executing your code once the dependencies have loaded. If you are using something like the Google Maps API that loads in multiple dependencies of its own there is even a plugin that will wait for all of the third party dependencies to load as well. There is a short write-up that shows you how to integrate AngularJS with RequireJS. As an added bonus, Require comes with an optimizer that you can run as part of your deployment build process to compile all of your local files into a single file.

what is the PHP equivalent of Javascript Number.MIN_VALUE?
Well, this is easy to calculate. Just divide 1.0 by 2.0 until reaching zero, the number right before zero equals the Number.MIN_VALUE. See this codepad PHP <?php $a = 1.0; while (1) { $b = $a; $a /= 2.0; if ($a == 0.0) break; } var_dump($b); ?> Output float(4.9406564584125E-324) But remember that this will give you the smallest positive number on the server not the client. If you want to interpret a number coming from client-side, you better just send Number.MIN_VALUE from the client to the server through a GET or POST request.

Javascript equivalent for curl command
cURL is able to send and receive data cross domain to remote servers but that is not the case with javascript for security reasons Your options I believe are 1) Use CORS to set headers on the remote server to accept cross domain calls (if you have access to the Server) as also pointed by thriqon 2) Use jsonP format response from the server(again if you have control over how the response is generated or if its already in jsonP format) 3) Write a server-side proxy that acts as the intermediary between your calls and the remote server. You can then format the header or response on the proxy to enable it to respond to cross domain calls

Javascript file object equivalent in java
It depends on what you want to store in your List. You can even choose to use List<?>, which will allow you to store almost anything in it. But if your attachment objects are of type Attachment, I'do go with List<Attachment>. That would allow you to store only Attachment objects in the list. Since in Javascript there are no classes, it might be worth to mention that in Java, every object is an instance of a "class". Sometimes you define classes yourself, sometimes you re-use classes inside a framework or library. So there is no general answer to the question, what type your elements will have.

Native javascript equivalent of jQuery :contains() selector
Well, jQuery comes equipped with a DOM traversing engine that operates a lot better than the one i'm about to show you, but it will do the trick. var items = document.getElementsByTagName("*"); for (var i = 0; i < items.length; i++) { if (items[i].innerHTML.indexOf("word") != -1) { // Do your magic } } Wrap it in a function if you will, but i would strongly recommend to use jQuery's implementation.

Python string.replace equivalent (from Javascript)

The first argument is match.group(0). The second one is match.group(1).

JavaScript Equivalent of Late Static Binding
In your JavaScript code, there's nothing static (or even "static-like"). To simulate static variables, you can attach properties directly to constructors: function my_pet(){} my_pet.name = "paulie"; function my_dog(){} my_dog.name = "stacey"; However, to achieve what you're looking for, you may want to use the prototype chain instead: function my_pet(){} my_pet.prototype.name = "paulie"; function my_dog(){ this.name = "stacey"; } my_dog.prototype = Object.create(my_pet.prototype); var stacey = new my_dog(); console.log(stacey.name); //stacey console.log(my_dog.prototype.name); //paulie delete stacey.name; // no more shadowing console.log(stacey.name); // paulie

Is there a Ruby equivalent for JavaScript's Function.prototype.bind?
Normally, rebinding methods isn't something you do in Ruby. Instead, you use blocks: # This is our receiver "R" def idiot(&block) puts("yes, master; #{block.call}") end # Here's a couple method "M" examples def calculateSomethingDifficult(a, b) return "the sum is #{a + b}" end def applyJam(object) return "adding jam to " + object.name end class Item attr_reader :name def initialize(name) @name = name end end # Here's how we might use it idiot do calculateSomethingDifficult(1, 1) end #=> yes master; the sum is 2 # You *can* change calling context too (see instance_exec), but I'd # discourage it.

What is the equivalent CSS in IE7?
Although you mention not wanting to use an IE7 hack, here is a valid way of creating IE7 only styles without adding additional style sheets, this will solve your problem, add the following code <!--[if IE 7 ]> <html class="ie7"> <![endif]--> <!--[if !(IE 7)]><!--> <html> <!--<![endif]--> in place of your usual html tag. You can then use: .ie7 .css-selector { to target any element in ie7 only. For full disclosure, this works for all versions of ie if you use conditional comments such as: <!--[if lt IE 7 ]> <html class="ie6"> <![endif]--> <!--[if IE 7 ]> <html class="ie7"> <![endif]--> <!--[if IE 8 ]> <html class="ie8"> <![endif]--> <!--[if IE 9 ]> <html cla

Is e1 && e2 equivalent to e2 && e1?
Logically, yes. e1 && e2 will never have a different result than e2 && e1 from a logical standpoint. But from a code standpoint, if evaluation of e1 or e2 has side effects, then no, they are not completely equivalent. Specifically, sometimes people use functions in a chain of &&. if( isHungry() && hasFood() ) eat() ; Usually you would want to put the cheapest to evaluation condition first, and only check the 2nd condition if the first condition held up as true. Short circuit evaluation is what guarantees this will happen. If the 1st condition in an AND logical operation is false, then the 2nd statement isn't even evaluated, because the end result won't be TRUE anyway (FALSE && (TRUE && TRUE && TRUE && TRUE)) == FALSE
