JS Calculator

gistfile1.js

var calculator() = function{

	this.multi() {
		var digs = 0;
		for (var i = 0, i < digs.length;  i ++) {
			digs *= digs.length[i];
                        {
		console.log(digs)
            }

	this.add() {
		var digs = 0;
		for (var i = 0, i < digs.length;  i ++) {
			digs += digs.length[i];
                        {
		console.log(digs)
           }

	this.subt() {
		var digs = 0;
		for (var i = 0, i < digs.length;  i ++) {
			digs -= digs.length[i];
                       {
		console.log(digs)
           }

	this.divi() {
		var digs = 0;
		for (var i = 0, i < digs.length;  i ++) {
			digs %= digs.length[i];
                        {
		console.log(digs)
           }

}

Ex.
var calc = new calculator();

calc.add([2,3]);

you're refrencing calc.add([2,3]); but this.add doesn't take any arguments.

also, you create object functions like this

this.add = function(digs) {
// fun fun
};
