js-partial-foreach

Synopsis

A partial to provide a better foreach capability in UMD. This foreach partial automagically detects whether the callback function expects one or multiple arguments similar to PHP's foreach construct by value or key-value distinction.

Works with compressed JavaScript code too, also compatible with ECMAScript 6 arrow functions.

Install

npm install js-partial-foreach

Usage

First, initialize/include the partial, then use it. The actual usage of the partial is the same across all environment.

Usage - Initialize/Include

• AMD (e.g.: RequireJS)

define(['js-partial-foreach'], function(foreach) {        
    // you can now use foreach
});

• CommonJS (e.g.: NodeJS)

var foreach = require('js-partial-foreach');

// you can now use foreach

• Browser

// load the source from "node_modules/js-partial-foreach/dist/js-partial-foreach.js" - for development
// or from "node_modules/js-partial-foreach/dist/js-partial-foreach.min.js" - for production

var foreach = js_partial_foreach; // it is available in the global namespace

// you can now use foreach

Usage - After Initialization

• With arrays

var array = [1, 2, 3, 4, 5];
    
foreach(
    array,
    function(value) {
        console.log(value); // 1 .. 5
    }
);
    
foreach(
    array,
    function(key, value) {
        console.log(key + ':' + value); // 0:1 .. 4:5
    }
);

• With objects

// for objects
var object = {
    a : 1,
    b : 2,
    c : 3,
    d : 4,
    e : 5
};
    
foreach(
    object,
    function(value) {
        console.log(value); // 1 .. 5
    }
);
      
foreach(
    object,
    function(key, value) {
        console.log(key + ':' + value); // a:1 .. e:5
    }
);

• With ES6 arrow functions

var array = [1, 2, 3, 4, 5];
   
foreach(
    array,
    (value) => {
        console.log(value); // 1 .. 5
    }
);
   
foreach(
    array,
    (key, value) => {
        console.log(key + ':' + value); // 0:1 .. 4:5
    }
);

• With strings

var string = 'abcdefgh';
   
foreach(
    string,
    function(char) {
        console.log(char); // 'a' .. 'h'
    }
);
