   For example, you can't get AST tree, you get a shorter version of the bytecode (yes, it can be even more detailed). So, if you want to get all the power, you should get a debug version of Node.Js. For quite a long time before, to achieve this you had to download all related source code for the engine you wanted and compile it by yourself.

   Ignition uses registers like r0, r1, r2 ... to store bytecode inputs or outputs and specifies which ones to use. Along with input registers, Ignition also has an accumulator register, which stores the results of operations, we'll call it acc. It's pretty much the same as common registers but operands do not specify it at all, for instance, sub r0 i...

   Let's take a real bytecode from a real function in JavaScript. We're not using our readFilefunction since it'd be too complicated. Let's use this simple function: This will generate the following bytecode: Let's ignore the header and the footer since it's just metadata for the bytecodes. LdaNamedProperty a0, , This bytecode loads a named property o...

   Most bytecodes may seem gibberish at first glance. But keep in mind that Ignition is a register machine with an accumulator, that is basically how we can simply understand how it works. This would be the bytecode for our readFilefunction: We can see it has a series of bytecodes specifically designed to several aspects of the language, such as closu...
