This is a very hastily cobbled together JSON prettifyer that doesn't bug me about input validity as long as unambiguous. Also it warns about a few validity issues (not all). #tool
{ Transform } = require('stream')
EOL = "\n"
Utils =
spaces: (num) -> if num <= 0 then '' else (new Array(num + 1)).join(" ")
ljust: (str, len) -> str + Utils.spaces(len - str.length)
streamToString: (stream, cb) ->
len = 0
buffer = []
stream
.on('end', -> cb(null, Buffer.concat(buffer, len)))

More exhaustive version of typeof #snippet_js
toString = Object::toString
hasOwnProperty = Object::hasOwnProperty
propertyIsEnumerable = Object::propertyIsEnumerable
toStringTags = date: '[object Date]'
Utils =
### @return `undefined|null|boolean|string|symbol|number|NaN|array|arguments|date|object|function` ###
type: (val) ->
switch type = typeof val
when 'undefined', 'string', 'boolean', 'symbol'
return type

what's `this` in javascript #tutorial

this

Function declarations

There are two (mostly) equivalent ways to define a function:

function Add(a, b) { return a + b };

var Add = function(a, b) { return a + b };

Better typeof
toString = Object::toString
hasOwnProperty = Object::hasOwnProperty
propertyIsEnumerable = Object::propertyIsEnumerable
### @return `undefined|null|boolean|string|symbol|number|NaN|array|arguments|date|object|function` ###
(val) ->
switch type = typeof val
when 'undefined', 'string', 'boolean', 'symbol'
return type
when 'number'
return (if Number.isNaN(val) || (val in [Number.POSITIVE_INFINITY, Number.NEGATIVE_INFINITY]) then 'NaN' else type)

Example for C users of how classes and virtual lookup tables can work. Proper memory and error management left out. #tutorial #oop

basic debug on object of type 'pointer', data: 0xdeadbeef
