ALLTHETHINGS.JS

Let your array iterations read like actual sentences:

var things = ['all', 'the', 'things'];

function log(thing) {
    console.log(thing);
}

log.allThe(things);

For no extra cost, you also get the 'fromThe' and 'inThe' aliases, for your grammatical needs:

var proHackers = filterNoobs.fromThe(hackers);
containsProHackers.inThe(hackers); // true

And all for less than 1KB, with no dependencies*. Delicious.

*Unless your browser is an antique. Then you need es5-shim.

ALLTHETHINGS.JS allows you to sentencify the following array methods:

Gimme gimme

Node.js

Install with: npm install allthethings

require('allthethings');

Browser

Download the production version or the development version.

forEach / map

By default, 'allThe' performs a map on the array, which doubles as a forEach:

forEach

var things = ['all', 'the', 'things'];

function log(thing) {
    console.log(thing);
}

log.allThe(things);

map

var numbers = [1,2,3];

function triple(number) {
    return number * 3;
}

var multiplesOfThree = triple.allThe(numbers); // [3,6,9]

filter

If your named function starts with 'filter' or 'is', then a filter is performed.

When filtering, it's idiomatic to use 'fromThe' instead of 'allThe':

var numbers = [-2,-1,0,1,2];

function filterNegatives(number) {
    return number >= 0;
}

filterNegatives.fromThe(numbers); // [0,1,2]
var numbers = [-2,-1,0,1,2];

function isPositive(number) {
    return number > 0;
}

isPositive.fromThe(numbers); // [1,2]

reduce / reduceRight

If your named function starts with 'reduce', 'calculate' or 'add', then a reduce is performed.

If you add 'Right' to any of these, then a reduceRight is performed instead.

When reducing, it's idiomatic to use 'fromThe' instead of 'allThe':

Given the 'numbers' array:

var numbers = [1,2,3];

Any of these will work identically:

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

var total = reduceTotal.fromThe(numbers); // 6
function calculateTotal(a, b) {
    return a + b;
}

var total = calculateTotal.fromThe(numbers); // 6
function addTotal(a, b) {
    return a + b;
}

var total = addTotal.fromThe(numbers); // 6

some

If your named function starts with 'some', 'contains' or 'has', then a some is performed.

When using 'some', it's idiomatic to use 'inThe' instead of 'allThe':

var numbers = [-2,-1,0,1,2];

function someNegatives(number) {
    return number < 0;
}

someNegatives.inThe(numbers); // true
var numbers = [-2,-1,0,1,2];

function containsNegatives(number) {
    return number < 0;
}

containsNegatives.inThe(numbers); // true
var numbers = [-2,-1,0,1,2];

function hasNegatives(number) {
    return number < 0;
}

hasNegatives.inThe(numbers); // true

every

If your named function starts with 'every' or 'all', then an every is performed.

When using 'every', it's idiomatic to use 'inThe' instead of 'allThe':

var numbers = [1,2,3,4,5];

function everyNumberIsPositive(number) {
    return number > 0;
}

everyNumberIsPositive.inThe(numbers); // true
var numbers = [1,2,3,4,5];

function allPositive(number) {
    return number > 0;
}

allPositive.inThe(numbers); // true

Elite hacker tips

Aliased functions

Assign a named function expression to a variable of a different name:

var things = [false, true, false];

var myAliasedFunction = function filter(thing) {
    return thing === true;
};

myAliasedFunction.allThe(things); // [true]

Custom function name rules

You can create new rules or override existing ones:

In Node.js

var allthethings = require('allthethings');

allthethings.rules.filter = /foobar/;

In the browser

window.allthethings.rules.filter = /foobar/;

Which allows:

var numbers = [1,2,3,4];

function foobar(number) {
    return number % 2 === 0;
}

// This now performs a filter:
foobar.allThe(numbers); // [2,4]

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
