Power of Declarative Programming

[canmingir]

Declarative Programming is everywhere even though we don't name them. SQL, HTML, regex, even JavaScript is declarative to C/C++, and C/C++ is declarative to assembly language so on so forth.

In this project, we took a different approach that usually declarative languages are defined in complete different set of language syntax, but I think the world has reached enough programming languages. Instead, we used exact same JavaScript syntax and but rerenders declaratively. For example:

> a = 1
> b = a + 2
> a = 2
> b
?

In imperative language like JavaScript, the b is 3 because variable b references to the memory location of a + 2, but if you run exact same thing in Nucleoid, the results is 4 because it is declarative. It means the declarative runtime does additional calculation when a is updated as adjusting a's dependencies like b.

One of advantages of repurposing the same JavaScript language syntax is this gives us an opportunity to extend what JavaScript offers, so that we can focus on controlling flow, applying logic programming and managing datastore while JavaScript is still runtime engine.
