Learn how to build you Bitcoin script interpreter in Javascript

[mriou]

I wrote this as a way to explain how Bitcoin scripts are evaluated. Javascript was chosen for as a language the interpreter as a lot of people can read it pretty easily. Thought it'd be useful for others here:

Interesting! Maybe you could add the standard output script to one of your examples? https://en.bitcoin.it/wiki/Script#Standard_Transaction_to_Bitcoin_address_.28pay-to-pubkey-hash.29

There is a similar description of script in JavaScript here https://curiosity-driven.org/low-level-bitcoin#script and a simple interpreter here: https://curiosity-driven.org/bitcoin-contracts

Bitcore library (also in Javascript) also has an existing ScriptInterpreter.
