Advanced tools
function-extended
is a Javascript library that can be used standalone or incorporated into extended
var fn = require("function-extended");
Or
var myextended = require("extended")
.register(require("function-extended"));
npm install function-extended
Or download the source (minified)
bind
Binds a function to the specified scope, while currying any extra arguments.
bindAll
Binds all functions or a list of named functions to the specified scope.
var scope = {
a: "a",
b: "b",
c: "c",
aFunc: function () {
return this.a;
},
bFunc: function () {
return this.b;
},
cFunc: function () {
return this.c;
}
};
fn.bindAll(scope);
scope.aFunc.call({}); //"a"
scope.bFunc.call({}); //"a"
scope.cFunc.call({}); //"c"
//or
fn.bindAll(scope, ["aFunc"]);
scope.aFunc.call({}); //"a"
scope.bFunc.call({}); //undefined
scope.cFunc.call({}); //undefined
bindIgnore
Binds a function to the specified scope while ignoring any extra arguments passed in.
var func = function () {
return [arguments.length, this.test];
};
var scope = {test: true};
var fn1 = fn.bindIgnore(obj, func, "hello"),
fn2 = fn(func).bindIgnore(obj, "hello").f(),
fn3 = fn(obj).bindIgnore(func, "hello");
fn1("world"); //[1, true]
fn2("world"); //[1,true]
fn3.f()("world"); //[1, true];
partial
Creates a function that does not change the eventual scope, but allows the you specify arguments that should be passed in.
var func = function (str) {
return str + " " + this.world;
};
var a = fn.partial(func, "hello");
var b =fn(func).partial("hello").f();
a.call({world: "world"}); //hello world
b.call({world: "world"}); //hello world
//With a string
var c = fn.partial("test"),
c2 = fn("test2").partial().f(),
var scope = {
test : function(){
return "hello";
},
test2 : function(){
return "world";
}
};
c.call(scope); //hello
c2.call(scope); //world
applyFirst
Binds the function to the first arguments passed in.
var func = function () {
return this.test;
};
var newFn = fn.applyFirst(func);
newFn({test: true}); //true
newFn = fn(func).applyFirst().f();
newFn({test: true});
var push = fn.applyFirst("push"), pop = fn("pop").applyFirst().fn();
var arr = [];
push(arr, 1);
//arr === [1];
pop(arr);
//arr === [];
curry
Create a curried function.
var curried = fn.curry(4, function(a,b,c,d){
return [a,b,c,d].join(",");
});
curried("a");
curried("b");
curried("c");
curried("d"); //"a,b,c,d"
//OR
curried("a")("b")("c")("d"); //"a,b,c,d"
