Coconut JavaScript (CocoJS)
CocoJS is a superset of a JavaScript (ECMAScript) subset. First, take a subset of JavaScript, and then superset it with optional typing annotations (using TypeScript's syntax and semantics for them).
Modules
CocoJS uses ES6-style modules.
An ES6 module is a special kind of script, which is just a file containing a list of top-level statements. CocoIL modules have a bit more structure to them to facilitate analysis and determinism. As a result, there is a mapping from CocoJS to CocoIL module structure.
The mapping simply records all declarations -- variables and functions -- and then moves all other statements into the
special module initializer (.init) function. In the case of blueprints, the special entrypoint function .main is
devoid of logic, because in Node.js-style of programming, the module initializer takes care of entrypoint functionality.
