Portable Node.js and NPM on windows
  1. Get node binary (node.exe) from http://nodejs.org/download/
  2. Create the folder where node will reside and move node.exe to it
  3. Download the last zip version of npm from http://nodejs.org/dist/npm
  4. Unpack the zip inside the node folder
  5. Download the last tgz version of npm from http://nodejs.org/dist/npm
  6. Open the tgz file and unpack only the file bin/npm (without extension) directly on the node folder.
  7. Add the the node folder and the packages/bin folder to PATH
  8. On a command prompt execute npm install -g npm to update npm to the latest version

Now you can use npm and node from windows cmd or from bash shell like Git Bash of msysgit.

Hidden classes in JavaScript and Inline Caching

Hidden classes in JavaScript and Inline Caching

Knowing how internals work is always a good. Pretty much for everything. Cars, trains, computers, you name it. It gives you an insight on what happens under the hood. You also act/react differently based on this knowledge.

As you might have guessed, it’s also true for web development. Knowledge of CSS transitions allows you to achieve better performance and not to use JavaScript in most cases. Knowledge of V8 internals allows you to write more performant JavaScript code. So let’s talk about V8 a little.

A little about V8

V8 is a JavaScript engine built by Google. Firefox built SpiderMonkey, Opera built Carakan and Microsoft built Chakra. One very important difference between V8 and other JavaScript engines is that V8 doesn’t generate any intermediate code. It compiles JavaScr
