JSMicro - Iterator

foreach(object, handler, reversed)

Iterate Array, Object, String, Number, and Arguments (and NodeList on browser), using direct mode.

• object - Array, Object, String, Number, or Arguments to iterate.
• handler - Function to handle the each items. Will get (key, value) for object, and (i, value) for non-object.
• reversed - Boolean does the iteration should be reversed. Default is no.

foreach(object).run(handler, reversed)[.then(handler)][.catch(handler)]

Iterate Array, Object, String, Number, and Arguments (and NodeList on browser), using waiting mode.

• object - Array, Object, String, Number, or Arguments to iterate.
• handler - Function to handle the each items. Will get (key, value) for object, and (i, value) for non-object.
• reversed - Boolean does the iteration should be reversed. Default is no.

.then(handler)

Add function that will be called when the iteration done.

.catch(handler)

Add function that will be called when the iteration is stopped.

Browser Usage

bower install --save jsmicro-foreach

<script type="text/javascript" src="bower_components/jsmicro-foreach/index.js">
<script type="text/javascript">
    // Iterating array.
    foreach([1,2,3], function(i, v) {
        console.log(i); // 0, 1, 2
        console.log(v); // 1, 2, 3
    });
    
    // Iterating object.
    foreach({a: 1, b: 2 }, function(key, value) {
        console.log(key); // a, b
        console.log(value); // 1, 2
    });
    
    // Iterating number.
    foreach(100, function(i, n) {
        console.log(i); // 0 - 99
        console.log(n); // 1 - 100;
    });
    
    // Iterating string using waiting mode.
    foreach('Test').run(function(i, char, next) {

        console.log(char); // T, e, s, t
        
        next();
    }).then(function() {
        console.log('Iteration done');
    });
    
    // Iterating number using waiting mode.
    foreach(5).run(function(i, n, next) {

});

// Iterating number and break the iteration.
foreach(100).run(function(i, n, next, stop) {
    console.log(i); // 0 - 49
    console.log(n); // 1 - 50
