Building V8 Javascript Engine. Introduction I was thinking sometime ago about starting hacking with V8, aside from the fact that I work every day with Javascript, is that the Chromium engineers are doing a very good job making V8 fast and efficient and for some task good Javascript code is faster than C++, here is a great talk about the sophisticated JIT generation in Javascript. After many days of procrastination, I put my hands-on and start the task of downloading the project and prayed that everything would just work, like many things in life it didn't work the first time, here I documented all the steps, if somebody wants to start playing with this, hopefully this will make their life easy.
