JavaScript call apply

Call
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call

var obj = {
  num: 2
};

var addToThis = function(a) {
  return this.num + a;
};

addToThis.call(obj,3);

the obj is passed to addToThis function which has "num" property. a is passed when call is made.


Apply
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/apply

var addToThis = function(a, b, c) {
  return this.num + a + b+ c;
};

arr = [1,2,3];
console.log(addToThis.apply(obj, arr);

the obj is passed to addToThis function which has "num" property. arguments  is passed in an array when apply is made

JavaScript Bind

Ex 1

var a = {name:"bob"};
var b = {name: "john"};
function showName(){return this.name;};
showName.bind(a)();
showName.bind(b)();

Ex 2

function add(x,y){

return x + y;
}

var plus1 = add.bind(null,1);
console.log(plus1(5));

var o = new msg();
console.log(o.first);

var logger = require('./logger/index.js');

add a new folder logger and default will be the index.js file, also js file extension can be ignored.

index.js
module.exports.log = function (msg){
    console.log(msg);
}

exports as constructor

app.js


console.log('Hello world');

//console.log(msg.second);

msgs.js as constructor

module.exports =function (){

console.log(x * y);
var msg = require("./msgs.js");

console.log(msg());

msgs.js
module.exports =function (){

Provider

Only type can be put in app.config

Can set values on service application wide before they can be injected to any part of application.

This.$get is required,  must return an object containing all public available methods

Variables attached to 'this' are able to set in app.config

'var' are not

Service vs factory, constant vs value

Factory return an object with methods
Service has to be initiated with new

Constant available during angularjs configuration phase

Value available during run time phase

Prototypal inheritance - page 53 AngualrJS for .Net developers in 24 hours,

Prototypal inheritance is a concept that gives a lot of JavaScript developers problems, especially coming from a classical inheritance background. It’s a vitally important concept, though. To read more about prototypal inheritance, check out the Mozilla Developer Network’s JavaScript Guide. It’s full of great information on JavaScript.

<!-- View without ControllerAs syntax that has nested scopes.-->
<div ng-controller="Order">
    <input type="text" ng-model="orderTotal" />
    <div ng-if="showDetails">
        <input type="text" ng-model="orderTotal" />
    </div>
</div>

You can avoid all of that mess by using ControllerAs syntax:
<!-- View with nested scopes, but with ControllerAs.-->
<div ng-controller="Order as vm">
    <input type="text" ng-model="vm.orderTotal" />
    <div ng-if="showDetails">
        <input type="text" ng-model="vm.orderTotal" />
    </div>
</div>

Now the two models explicitly share the same scope of the controller’s alias, vm, and we’ve tamed the scope craziness.

Angular JS module, controller, $scope

ng-app defines the module name

angular.module to construct the module

you will also put dependencies in []

inside module has controller

controller is also on html file (this portion of web page is in my control with my $scope)

$scope send data over to html file using {{xxxx}}

xxxx is inside $scope

display data on web page.

Uncaught Error: [$injector:nomod] Module 'xxxx' is not available!

http://www.johnpapa.net/easy-fix-to-a-common-angular-module-error/

Correct line
angular.module('musicApp',[])

Incorrect line

angular.module('musicApp')

You need to have ",[]" when specify a module

Uncaught Error: [$injector:nomod] Module 'musicApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
http://errors.angularjs.org/1.4.9/$injector/nomod?p0=musicApp
angular.js:4470 Uncaught Error: [$injector:modulerr] Failed to instantiate module musicApp due to:

http://errors.angularjs.org/1.4.9/$injector/nomod?p0=musicApp


the something in `ng-app="something"` in your html must match the name of your main app module.

I got the same error, but it was because I forgot the angular.module("name", [])
you cant forget the [] or it wont inject and dependencies.

below is the app.js file

angular.module('musicApp',[])
.controller('ArtistController', ['$scope', ArtistController]);
function ArtistController($scope) {
    $scope.artist='Foo'
}

below is the index.html file
