Node.children is a read-only property that returns a live HTMLCollection of the child elements of Node.

Syntax 

var children = node.children;

children is a HTMLCollection, which is an ordered collection of DOM elements that are children of node. If there are no element children, then children contains no elements and has a length of 0.

Example

var foo = document.getElementById('foo');
for (var i = 0; i < foo.children.length; i++) {
    console.log(foo.children[i].tagName);
}

Polyfill

// Overwrites native 'children' prototype.
// Adds Document & DocumentFragment support for IE9 & Safari.
// Returns array instead of HTMLCollection.
;(function(constructor) {
    if (constructor &&
        constructor.prototype &&
        constructor.prototype.children == null) {
        Object.defineProperty(constructor.prototype, 'children', {
            get: function() {
                var i = 0, node, nodes = this.childNodes, children = [];
                while (node = nodes[i++]) {
                    if (node.nodeType === 1) {
                        children.push(node);
                    }
                }
                return children;
            }
        });
    }
})(window.Node || window.Element);
