what is javascript-fu?
javascript-fu is a martial arts discipline (library) for node.js and the browser. through mastering the art of javascript-fu you will be a nimble, yet powerful JavaScript developer. a true javascript-fu master can avoid the bad parts of javascript with ninja-like agility and perform quick and devastating blows to produce robust, succinct code that covers a myriad of common functionalities.
where did javascript-fu come from?
javascript-fu is the culmination of years of training in the archaic art of javascript. through meticulously studying the following ancient scrolls we have divined the ultimate form of javascript martial arts.
Underscore.js, jQuery.js, date.js, Rails Inflectors,
Coldfusion's DateFormat and TimeFormat, Microsoft's LINQ
how do i use javascript-fu?
if you don't like reading documentation, check out the interactive javascript-fu demo
browser
<script src = "js-fu.js" type = "text/javascript"></script>
<script>
var x = fu.isNumber(13); // true
var x = fu.isDate('07/01/2010'); // true
</script>
node.js
var fu = require('./js-fu');
var x = fu.isNumber(13); // true
var x = fu.isDate('07/01/2010'); // true
once you have required the js-fu library, you have access to the "fu" object. inside this object you will find ...
the five disciplines of javascript-fu
isFu - the art of the curious type checker
isFu methods will accept anything as an argument and gracefully return true or false depending on if the arguments match the type you have checked for
- isArray
- isBoolean
- isDate
- isDefined
- isEmpty
- isEqual
- isFunction
- isJSON
- isNode
- isNull
- isNumber
- isObject
- isRegExp
- isString
- isText
toFu - the deadly art of the monkey punch
toFu methods will accept anything as an argument and aggressively attempt to coerce the value into the type you have specified
- toCamel
- toChain
- toDash
- toHuman
- toJSON
- toLink
- toMix
- toNumber
- toOrdinal
- toParam
- toPercent
- toPlural
- toReverse
- toShuffle
- toSingle
- toTitle
- toTrim
- toUnderscore
- toWrap
getFu - the art of the swift getter
- getFirst
- getFunctions
- getIndex
- getKeys
- getLast
- getLeft
- getLinks
- getNode
- getRandom
- getRight
- getValues
dateTimeFu - the art of space and time
Try out the interactive demo of Date.format()
dateTimeFu adds a new method "format" to the built in JavaScript Date object
Date.format() takes one argument, a formatting mask
you can use a pre-defined formatting mask or an inline mask. you can also define new re-usable masks
var now = new Date();
now.format("shortDate"); // ouputs: 7/1/10
now.format("mm/dd/yyyy"); // outputs: 07/01/2010

linqFu - the forbidden art of querying JSON with LINQ, liberated from...Microsoft
Try out the interactive demo of JSLINQ
linqFu is adds the JSLINQ project which is a pure javascript implementation of gasp Microsoft's LINQ query language. it's very usefull for quickly querying JSON objects.
simple Select
var sample = fu.linq(sampleData).
Select(function (item) {return item.FirstName;});
output: {"items":["Chris","Kate","Josh","John","Steve","Katie","Dirk","Chris","Bernard","Kate"]}
simple Select with OrderBy
var sample = fu.linq(sampleData).
Select(function (item) {return item.FirstName;}).
OrderBy(function (item) {return item;});
output: {"items":["Bernard","Chris","Chris","Dirk","John","Josh","Kate","Kate","Katie","Steve"]}
simple Where
var sample = fu.linq(sampleData).Where(function (item) {return item.FirstName == "Chris";});
output: [
{"ID":1,"FirstName":"Chris","LastName":"Pearson","BookIDs":[1001,1002,1003]},
{"ID":8,"FirstName":"Chris","LastName":"Stevenson","BookIDs":[4001,4002,4003]}
