Can't able to understand where I made a mistake kindly let me know what's my mistake in the procress of learning :-)
Here this code is implementing to upload a file.
It's a syntax error else any coding error
(function() {
var app = angular.module("mode", ['ngFileUpload']);
app.controller("simCntrl", ['$scope', '$timeout', 'Up-load', function($scope, $timeout, Upload) {
// $scope.var = 10;
$scope.loadFile = function(files, errFiles) {
// alert('hi loaded');
$scope.files = files;
$scope.errFiles = errFiles;
angular.forEach(files, function(file) {
file.upload = Upload.upload({
url: 'https://angular-file-upload-cors-srv.appspot.com/upload',
data: {
file: file
}
});
file.upload.then(function(response) {
$timeout(function() {
file.result = response.data;
});
}, function(response) {
if (response.status > 0) {
$scope.errorMsg = response.status + ':' + response.data;
}
}, function(evt) {
file.progress = Math.min(100, parseInt(100.0 * evt.loaded / evt.total));
});
});
}
}]);
})();

Getting output as Expressions as follows...

{{f.name}} {{f.$error}} {{f.$errorParam}}
Fixed your file system links, the wrong module dependency Up-load and a typo fiels instead of files.
You got the {{}} curly braces because your app didn't bootstrap, it was waiting for the dependencies it didn't get.
var app = angular.module("mode", ['ngFileUpload']);
app.controller("simCntrl", ['$scope', '$timeout', 'Upload', function($scope, $timeout, Upload) {
$scope.loadFile = function(files, errFiles) {
$scope.files = files;
$scope.errFiles = errFiles;

file.upload = Upload.upload({

I am very new to angular js and I have been hanging around with api. The following code shows the name of the user and the name of the user when it is clicked. What I'm trying to do is I want the user to get the todos title when the button is clicked. https://jsonplaceholder.typicode.com/todos. how can I do that ? I know it's a bit confusing, but I'm waiting for you guys.

I write your code like this:
var app = angular.module('myApp', []);
var root = 'http://jsonplaceholder.typicode.com/users';
var todos= 'https://jsonplaceholder.typicode.com/todos'
app.controller('customersCtrl', function($scope, $http) {

});
$scope.getResult = function(item) {
$scope.titleList = [];
$http.get(todos).then(function (response) {
$scope.todosList = response.data; }).then(()=> {
$scope.todosList.map(it=> {
if (it.userId === item.id){
$scope.titleList.push({title: it.title , id: it.userId});
}
});
});
};

Main page URL: http://localhost:3000/
Current second page URL: http://localhost:3000/#/titleDetails.html
Expected second page URL: http://localhost:3000/titleDetails.html
Currently when I click on the title in my main page, the URL contains an extra /# which causes the page to be redirected to titleDetails.html.
The directory of titleDetails.html and index.html is in the same directory.
May I know how can I fix this?

I want that in the init to bind the model of my controller the init is called but I don't see any data what is wrong ?

Since you used jquery to get your data, you need to run a .$apply() as the code happened outside of angulars knowledge
$.getJSON('data/database.json', function (data) {
that.data = data;
$scope.$apply();
});
Alternatively you should not be using jquery at all and instead inject $http in (like you did with $scope) and use that:
$http.get('data/database.json')
.success(function(data){
that.data = data;
});
Additionally change the following:
$scope.showCategories = function () {
$scope.showCategories = true;
}
$scope.showWords = function (category) {
that.currentWords = [];
$scope.showCategories = false;
that.data.words.forEach(function (word) {
if (word.categoryId === category.id) {
that.currentWords.push(word);
}
});
}
and your html to:
<div id="categories" ng-show="showCategories">
<ul data-role="listview" data-inset="true">
<li ng-repeat="category in ctrl.data.categories">
<a ng-click="ctrl.showWords(category)" href="#">
<img src="images/Can_I.png">
<h1>{{category.name}}</h1>
</a>
</li>
</ul>
</div>
<div id="words" ng-show="!showCategories">
<ul data-role="listview" data-inset="true">
<li ng-repeat="word in ctrl.currentWords">
<a ng-click="ctrl.showMovie()" href="#">
<img src="images/Can_I.png">
<h1>{{word.name}}</h1>
</a>
</li>
</ul>
</div>
<div>
<input id="upBtn" class="ui-block-a" type="button" value="UP" ng-show="!showCategories" ng-click="ctrl.showCategories()">

Why is a get request fired 4times when I visit the page? It should only be fired 2times? Anyone who can explain?
Because you are defining firstPageController twice. First in the body tag, and then in the route.
I followed tutorial on this LINK to create AJAX requests on my angularJS appliction (CRUD operations). After I finished coding I tried to perform AJAX request (get all data from database) but when I lunch my application I got this error:
TypeError: undefined is not a function
at new <anonymous> (http://localhost:49510/Scripts/application/controllers.js:4:15)
Does someone knows where's the problem and how to fix it?
Here is code:
controller:
app.controller('ContactsController', [
'$scope', '$http', '$location', 'contactsService',
function ($scope, $location, $http, contactsService) {
$http.get('/contacts/').success(function (data) { //triggers error
alert(data);
$scope.contact = data;
$scope.loading = false;
})
.error(function () {
alert ("An Error has occured while loading contacts!");
// $scope.loading = false;
});
$scope.editContact = function (id) {
$location.path('/edit-contact/' + id);
};
$scope.displayContact = function (id) {
$location.path('/display-contact/' + id);
};
$scope.showDetails = function (id) {
var el = angular.element(document.getElementById('#ct-details-' + id));
el.toggleClass('details-hidden');
}
}
]);
and here is contacts.html template:
<div class="container view">
<header>
<h3>Contacts</h3>
</header>
<div>
<a class="nav-pills hover" href="#/add-contact">Add Contact</a>
</div>
<br /><br />
<div class="row">
<ul class="span5" >
<li class="nav-pills nav-stacked contact-row" data-ng-repeat="contact in contacts | orderBy:'firstName'">
<span id="ct-details-{{contact.id}}" data-ng-click="displayContact(contact.id)" style="cursor:pointer;" class="contact-data details-hidden" href="" >
<span class="span3 contact-name" >{{contact.firstName + ' ' + contact.lastName}}
{{contact.emailAddress}}</span>
</span>
<button class="btn editContact" data-ng-click="deleteContact(contact.id)">Delete</button>
<button class="btn editContact" data-ng-click="editContact(contact.id)">Edit</button>
</li>
</ul>
</div>
</div>
and here is index.cshtml file:

The order of arguments in the controller function has to match the order in the parameter array.
You have mixed the order of $http and $location.
So change your function signature to
app.controller('ContactsController', [
'$scope', '$http', '$location', 'contactsService',
function ($scope, $http, $location, contactsService) {
