Want to hire freelance AngularJS developers on your own? Here are the skills you must look for while hiring an AngularJS developer

Hiring freelance Angular.js developers might be an intricate task for you if you are a non-technical manager. Today, Angular is one of the most demanding skills in the IT industry, and hiring the best freelance Angular developers among the thousands of developers is a challenging task for anyone. So, here Ultragenius comes to assist you while recruiting the top freelance Angular developers on your own. Ultragenius understands your job requirements and gets you only the top Angular freelancers who have in-depth knowledge of software development.

The following skills you must look for while hiring anĀ Angular freelancer –Ā 

Familiarity with the core HTML, CSS, and Javascript

Angular.js is one of the best front-end frameworks to use only if a developer is skilled in HTML, CSS, and Javascript. The developer must know more than one Javascript library framework like jQuery, Bootstrap and must be specialized in working with Asynchronous Javascript and XML (AJAX). Check if the developers have worked with Leaner CSS and Syntactically Awesome Stylesheet (SASS), also with Javascript build tools such as Grunt.js, Gulp.js, and Bower.js.

Javascript fundamentals + ECMAScript 6 -

Javascript is most widely used language in developing dynamic web applications and helps a developer integrate back-end with the front-end easily. TheĀ freelance AngularĀ developerĀ must be clear with the fundamental concepts of Javascript language and these ES6 skills –Ā 

  • Arrays and objects
  • Array methods
  • Functions and arrow functions
  • DOM Manipulation and event handler
  • The ā€œthisā€ keyword
  • The ā€œclassā€ keyword
  • Prototype chain and object creation
  • Higher-order functions and callback functions.
Well conversant with JS build tools

While working with real-world projects, Angular developers need to install many packages and add dependencies, file watcher, browser reloader, and many more. The developers must have the knowledge of webpack , npm, and yarn.

Very good understanding of testing frameworks and tools

Rising quick-deployment needs during the development phase, testing has become anĀ  important skill for Angular developers. Therefore, the developers should know about Jest, Enzyme, Mocha, Chai, AVA, and Tape for unit testing.

For end-to-end testing, they must know about Selenium, Webdriver, Cucumber.js, Nightwatch.js, Cypress, and Puppeteer.

For integration testing, they must know about Karma.

Experienced in working with Version Control System (VCS)

Developers must have a very good knowledge of version control systems, like Git, SVN, TFS, and Mercurial. Mostly, developers use Git for their work. It is the version control system that helps the team in collaborating and organizing your code, maintain the frequent changes that occur in the code. Git helps in reviewing the old codes and compares them with the newly updated code, pulling the code from their repository, and managing the commit history.

Along with this, the developer must know how to use add, push, pull, and commit commands, branching, and merging as it allows developers to work independently on the code.

Knowledge of MVC architecture

Angular developers must know about Model-View-Component (MVC) architecture. MVC approach helps you to create applications that separate the input logic, business logic, and UI logic while maintaining the loose coupling between the elements.


RxJS is the library used in Angular to perform tasks such as making HTTP requests and for providing the consistent API to perform asynchronous tasks.

Well versed in Typescript

Typescript includes strong typing which means that each expression has a data type that is determined at the compile-time and only operations designed for that data type are allowed. Angular is written in Typescript, as it specifies the variables and functions that were intended to be used at the compile time only, so you must check the developerā€™s knowledge of Typescript.

Immense knowledge of Angular and Dependency Injection

An angular developer should possess extensive knowledge of working with Angular and must be updated about the newest version of Angular and the latest features and functionalities that are recently added.

Dependency Injection (or DI) is the core part of any web application. DI is a design pattern in which a class takes or requests components from external resources rather than creating the components. This enables the developer to replace the components without changing the class that uses them. Make sure the developer knows about Injector, Provider, and Dependency.

Experience with web markup and UI, UX Concepts

The developer must have a firm understanding of element positioning, displaying the elements, and making components interactive, semantic markup, and other related UX Concepts so they can design the product with the best quality. The developer must be experienced in developing visual effects in presentational markup. For, example – How the heading appears, making text larger and putting weight to it, and giving which color to it, and which markup can include captions, bind columns, and row headings to table cells.Ā 

Experience developing RESTful API(s)

A developer must know what REST – API(s) that are used in HTTP requests using GET, PUT, POST, and DELETE methods, which enable developers to read the web application more clearly and use it effectively.

Proficient in writing optimized and readable code

You must hire the developers based on their ability to write clean and optimized code that is understandable by all the team members, and is scalable.

Top Interview Questions to ask while hiring a freelance Angular.js developer

The core features of Angular mainly include :Ā 

  • Data BindingĀ 

Angular.js provides the data binding functionality which is the core feature of object-oriented programming.

  • Scope

Angular provides the ā€œ$scopeā€ object which binds the HTML view and Javascript controller.Ā 

  • Controller

Angular.js provides the Javascript function to maintain application data and behavior using scope objects.Ā 

  • Services

Services are singleton objects that are created only once during the lifetime of an application. Services contain several methods that maintain data throughout the lifetime of an application. For example, $http which helps in making XMLHttpRequests and AJAX calls.

  • MVC Pattern ArchitectureĀ 

Model-View-Controller (MVC) architecture supports fast and parallel software development. One developer can work on the view while the other can work on the controller. So Angular implements MVC by allocating the responsibilities properly.Ā 

  • Filters

Angular.js provides the ā€œfiltersā€ to filter the array elements and objects and return the filtered array.

  • Dependency Injection

Angular.js provides the core function of dependency injection where one object can provide the dependencies for other objects. This feature helps developers to develop, maintain, and test web applications quickly by making the class implement the single responsibility principle.

  • Directives

Directives represent the classes that add additional behavior to elements, attributes, and CSS.Ā 


The scope is a built-in binding part that connects HTML (view) and Javascript (controller). Scope defines the model component in the MVC architecture.Ā 


Directives are the built-in classes that provide new behavior to the DOM elements like comments, CSS classes, names, and attributes. There are different types of directives in Angular which are used to manage styles, lists, and forms.

  • Components - Components are template directives.
  • Attribute directives - These directives change the look or behavior of any attribute, component, or element.
  • Structural directives - These directives change the DOM layout by adding and removing the DOM elements.


Data binding is the process of communication between the typescript code of your component and the template with which the user interacts.

For example, ngModel, if you change any data in your model, then the view gets updated automatically and vice versa is also true.

Data binding is of two types, namely -Ā 

  • One-way data binding - It is the type of data binding in which any change made in the Typescript code (model) is reflected in the HTML template (view) well. But you cannot update the model from the view. Angular Interpolation, Event Binding, String Interpolation, and Property Binding are examples of One-way data binding.Ā 
  • Two-way data binding -Ā  In this type, there is the automatic synchronization of the data between model and view. The HTML template and the Typescript code remain updated all the time and any change made in the model is reflected in the view and vice-versa.

$rootScope is the scope object which is available in the entire application and will be shared among all the components of the application. There is only one $rootScope in the whole application. ā€˜$rootScopeā€™ is the parent object of all other scope objects.

The $$ syntax defines the private variables in Angular.js. Developers use it to avoid unexpected code changes due to exposure to variables. Examples are $$childScope, $$watchers, and $$observers.

The $ syntax defines the built-in core Angular parameters, variables, and functions such as $scope, $http, $watch, $routeProvider, etc.

If the condition specified within is not satisfied, the ng-if directive does not render the element and the elementā€™s scope gets destroyed, on the other hand, ng-show directive renders the element but hides its display with ng-hide.


$scope.$watch() function is used to watch the new and the old values of the expressions. Two function parameters are passed in the watch function namely,Ā 

  1. Value function
  2. Listener function

The value function returns the value that is being watched and AngularJS determines if the value is different from the last returned value from the watch function. The listener function must do whatever it is acted upon.

Angular interpolation is used to display componentsā€™ data inside the double curly brackets in its respective HTML template. Angular Interpolation transmits data in one direction only, i.e., from components to HTML template.Ā 

It is used to -Ā 

  1. Display and identify the strings between HTML element tags and within attribute assignments,Ā 
  2. Evaluate arithmetic expressions contained within curly brackets,Ā 
  3. Used with ngFor directive to display an array of objects, andĀ 
  4. Call methods on hosting component views within interpolation expressions.Ā
