// Minimal FRP Behaviors and Events.

// An event function is any function of shape `function (next) { ... }` where
// `next(value)` is a callback to be called by event function. Transformations
// of event are accomplished by wrapping event with another event function,
// and consuming original event within (CPS).

// A behavior is any function of shape `function (time) { ... }`, where
// `time` is current time. Behaviors may capture state, return value from time,
// or be constant. Behaviors must always return a value, but value may

Make linting great again!

No other topic in software development probably has so much controversy as linting.

With a wrong workflow linting can be really a pain and will slow you and your team down. With a proper setup, though, it can save you hours of manual work reformatting the code and reducing the code-review overhead.

Parser

• /src/parser/spider_monkey_ast.ml: The type definitions for the AST. Tries to stay very close to ESTree
• /src/parser/lexer_flow.mll: The ocamllex lexer logic
• /src/parser/parser_flow.ml: The recursive descent JS parser

Inference

• /src/typing/type_inference_js.ml: Contains the "entry point" for inference (Function called infer_ast).
• /src/typing/statement.ml: Most of the inference logic (runs through the AST and generates the initial constraints)

While I was experimenting with animation, I had to make a few basic prototypes for a layout system and see how they intertwine. Here's the API in conjunction with React:

var MyComp = React.createClass({
  registerLayoutValues: function() {
    return {
      self: {
        width: 30,
        left: (get('parent', 'width') - get('self', 'width')) / 2 // Center.
 }

<ViewList animator> // passes context: { step: 0.555 }
  <View /> // extends context with { index: 0 }
  <View /> // ...
  <View>  // extends context with { index: 2 }
  
    // here's the tricky part: you can nest ViewLists, and they should pass their "new" context down to their children
    <ViewList> // reset context { step: 0 }
      <View /> // reset context { index: 0 }
    </ViewList>
