jitedjs

A new javascript engine with just in time compiler tech inside.

This is a project trying to create a javascript virtual machine (VM) from scratch.

Project Targets

• Milestone 1. Create a VM for a subset of javascript language (js-minus) running inside a interpreter
• Milestone 2. Update the interpreter to use just in time compiler.
• Milestone 3. Introduce some of the builtin functions (such as some pow)
• Milestone 4. Update the js-minus languague to full versioned javascript language (should be break down into some smaller targets)
• Milestone 5. Try sunpider / v8 benchmark.
