Bro, do you even javascript?

Features

You've got a deeply-nested set of objects that may or may not always be there. We've all seen something like this: var myURL = app.config.environment.buildURL('dev'); which leads to one of our favorite javascript errors... error: undefined is not a function

And the solution only makes the code base ugly:

var myURL;
if (app && app.config && app.config.environment && app.config.environment.buildURL) {
    myURL = app.config.environment.buildURL('dev');
}

We all hate that, don't we?

So what if you could just type:

var myURL;
if (Bro(app).doYouEven('config.environment.buildURL')) {
    myURL = app.config.environment.buildURL('dev');
}

Or better yet, how about:

var myURL;
Bro(app)
    .iDontAlways('config.environment.buildURL')
    .butWhenIdo(function(buildURL){
        myURL = buildURL('dev');
    });

Well, now you can!

But what if you have something like this:

app['soap:Envelope']['soap:Body'][0].getResponse[0]['rval'][0].customerId[0]

We got you covered.

if (Bro(app).doYouEven("soap:Envelope.soap:Body.0.getResponse.0.rval.0.customerId.0")) {
    var thisVar = app['soap:Envelope']['soap:Body'][0].getResponse[0]['rval'][0].customerId[0];
}

Features

Testing nested members

if(Bro(object).doYouEven('lift') === Bro.TOTALLY) {
    console.log(object.lift);
}

Or, ensure that multiple nested members exist by passing an array of paths

if (Bro(object)
    .doYouEven(['property.one', 'property.two']) {
    // returns true if all referenced properties exist
    console.log(object.property.one, object.property.two);
})

Or, just use a callback...

Bro(object)
    .doYouEven('property.subproperty', function(subproperty) {
        console.log(subproperty);
    });

Fetching nested members

// get a value if it exists
var value = Bro(object).iCanHaz('cheezeburger');

// get an array of values for paths that exist
var values = Bro(object).iCanHaz(['cheezeburger', 'money', 'beer']);

Creating nested members

// add properties to an object
Bro(object).makeItHappen('cheezeburger.with.pickles');
// set a deeply nested property by the Bro string
Bro(object).makeItHappen('bro.props', 'high five');  // object.bro.props = 'high five'

Calling nested functions

Bro(object)
    .iDontAlways('method')
    .butWhenIdo(function(returnVal) {
        console.log('object.method() returned ', returnVal);
    });

Handling exceptions

Bro(object)
    .braceYourself('method.name')
    .hereComeTheErrors(function(e) {
        console.log('error ' + e + ' happened.');
    });

Bro-oleans

Bro.TOTALLY // true;
Bro.NOWAY   // false;

Check for undefined

if (Bro(someVar).isThatEvenAThing() === Bro.TOTALLY) {
    // do stuff
}

Get a list of object keys

var object = {foo: 1, bar: 2};
Bro(object).giveMeProps();
// returns ['foo', 'bar'];

Extending objects

var obj1 = {foo: 'boo', bar: 'bar'},
    obj2 = {foo: 'bar', yes: 'no'};
Bro(obj1).comeAtMe(obj2);

// now obj1.foo == 'bar' and obj1.yes == 'no'

Extending Brototype!

Yes, extend me, Bro!

var plugin = { foo: function() { whatever; }};
Bro.prototype.comeAtMe(plugin);
