Hire Angular.js Developers in 48 Hours

As of 2022, Angular is one of the most popular web frameworks among developers worldwide. According to Statista, it takes 5th place with 20.39% of coders using it. Unsurprisingly, big companies like Gmail, Forbes, Upwork, and PayPal hire Angular developers. We’ll be talking about Angular’s earliest version, its predecessor that has been just as popular before the release of Angular 2+ and is still a good technology for software development.   

What makes AngularJS web framework so good? When should you pick it for a project’s front-end? And what should a good AngularJS developer know to be a good addition to the team? Read on to see the answers!

The Nuts and Bolts of AngularJS Development: An Asset for Building Dynamic SPAs

AngularJS is an open-source JavaScript framework, designed for developing single-page applications — websites that aren’t reloading when something is changing: like Twitter. AngularJS in particular was being used for Gmail and Google Drive. 

Google developed it in 2009. Even though after 13 years of development, Google discontinued the AngularJS version of the framework, it is still being used by many web developers. 

Angular JS Enables Easy Testing, Bug Fixes, and Updates

AngularJS is built on the MVC framework (or design pattern) which is widely used for developing rich web applications that are easy to maintain and test. Dedicated AngularJS developers separate your web app, through the framework, into three parts:

• Model (data) 
• View (the UI layer)
• Controller (business logic)

With architecture like this, Angular JS engineers create a solid foundation for application development, with its main components divided to enable testability. They utilize this construction to cut time for bug fixes, QA, deliver updates to their projects faster, and maintain high code quality. 

AngularJS Programmers Can Work Very Quick 

Two-way binding is one of the main benefits of using AngularJS. Apart from using the incredibly flexible MVC design, AngularJS synchronizes data with the UI layer to update the View, and when UI changes, the Model updates as well — and vice versa. Without two-way data binding, AngularJS developers would need to spend a lot of effort synchronizing data with the UI layer. 

Apart from that, AngularJS has directives, a feature that helps developers set behavior for UI elements, which greatly aids in building beautiful, high-performance web apps. 

Angular JS’ Toolkit Helps to Increase Developers’ Productivity

Another advantage of AngularJS is it allows for dependency injections (DI). It is a process of connecting dependencies to a component instead of making the component construct them — in other words, hardcoding them. AngularJS’ service locators can search for these dependencies and isolate them. That helps, for instance, to separate component classes for unit testing. 

This feature makes the startups’ apps maintainable and testable and, again, cuts development time. This is especially cool given that 6% of young projects fail because of delayed time-to-market.

What Products Angular.js Developers Build Most Often

AngularJS software developers can build several different types of web apps. The most common types of them are as follows:

Dynamic web applications (SPAs). Primarily, AngularJS is used for building dynamic web applications (SPAs). The framework turns HTML pages — the pages in the markup language of the web — into dynamic content, which makes SPA development extra easy for a dedicated AngularJS development team.

Enterprise-level applications. AngularJS developers can also build great enterprise-level applications. The Guardian’s website is an AngularJS application. To create an infinite scroll of search results, the developers used AngularJS with RxJS extensions for reactive programming. AngularJS is also used in Grid, the publication’s image management system. It stores over 3 million images and about 20,000 are added daily. 

Video streaming applications. Video streaming applications are another option for AngularJS development. One of the best examples of how Angular js developers can use it is within the YouTube app for PS3. 

Real-time data applications. AngularJS developers are also often proficient in building apps that do real-time data streaming — for example, Weather.com. The platform uses a large number of widgets that need to be downloaded for both the desktop and mobile versions of the site. Data gathering for widgets is done via AngularJS modules.

Angular.js Experts: Skills and Responsibilities

To supplement your existing team and hire an AngularJS developer you should be familiar with their core skills and responsibilities. This must be an expert JavaScript programmer with a thorough understanding of AngularJs software engineering.

Skills of AngularJS programmers

Here is what your top AngularJS developers should know/have/be familiar with:

• Degree in computer science, software engineering, information technology, or related disciplines
• Knowledge of AngularJS and front-end development tools such as Bootstrap and CodePen
• Know how to handle version control within GIT and how to use it in general;
• Knowledge of JavaScript frameworks
• Thorough knowledge of databases, APIs, and other online services;
• Critical and logical thinking skills
• Experience with unit testing tools such as Jasmine (to create tests) and Karma (to run them)
• Basics of behavior-driven development and test-driven development. 
• Knowledge of a clear chain of dependencies in terms of both application logic and relationships between files
• Proficiency in HTML, CSS, and JavaScript
• Familiarity with the newer ECMAScript specifications

The best of all is to hire a dedicated team of professionals that would include front-end Angular.js developers and back-end coders who know Node.js, MongoDB, and Express.js. A common JS ecosystem will boost development as different elements of the app will share language and logic.

Responsibilities of AngularJS experts

Now let’s see the AngularJS developer’s core tasks:

• Develop applications in AngularJS
• Debug the application
• Review the code of other team members
• Evaluate tasks issued by a business analyst, PM, or TL
• Participate in the expert assessment of the requirements for the task with the rest of the product team
• Perform tasks within the requirements, build apps according to the layout design;
• Work with various APIs 
• Indicate what can be improved in the product or workflow
• Collaborate with backend engineers
• Conduct unit tests and other tests

And while a decent engineer can perform all of them it is still better to think of several coders of different levels in your team.

How to Hire a Professional Angular.js Developer

To assess a particular AngularJS developer’s skills, follow the instructions below!

Questions to Ask Angular.JS Developers

AngularJS developers need to know JavaScript and the AngularJS framework itself expertly. They also need to be good communicators, be able to work efficiently in the team, know to ask questions when they’re stuck, and so on. 

Tech Skills Assessment for Freelance Angular js Developer 

The most common questions that will reveal the basic skills of the best AngularJS developers are:

High-level general questions: 

• What are the advantages of AngularJs over React?
• What is the most fascinating thing about Angular?
• What is the difference between Angular 2+ and AngularJS?

Questions for junior Angular JS developers

What is the main goal of Angular JS design?

The way Angular JS code is structured makes testing as easy as writing code is, which helps prioritize the former. Testability of the app is also boosted by the division between operations with DOM and the construction of the app’s internal logic. So, the goal of Angular JS design would be to make testing and development of SPAs equally simple and efficient. 

What’s your favorite thing about AngularJS?

Candidates answer such questions differently — they love different things about Angular JS — but look for “whys” of their answer, e.g. “Angular JS provides tools for preventing cross-scripting attacks which boosts the security of the app”.

What is AngularJS primarily used for?

Angular.js is commonly used for SPA development, which stands for Single Page Applications.

Questions for middle Angular JS developers

What is One-Time Binding and when is it used?

When you add an expression to a template using the “::” operator, which is called “one-time binding”, it means a program doesn’t need to activate a watcher. In simple terms, that means that one-time binding allows using Angular JS as a simple templating tool as opposed to the framework that’s one of the best for building SPAs. It’s used when developers know there’ll be no user-generated changes on the page, for instance, if they want to simply display a list of products in an e-commerce solution. The info on how to optimize one-time binding for different cases can be found, e.g., here. 

Briefly describe how the Angular.js digest loop works

The “digest loop”, also known as “dirty checking”, is a recursive loop that runs according to pre-set instructions to check watchers that monitor changes in variables and their values. After each digest cycle, the changes in the model are reflected in the DOM.

What is service in AngularJS?

Services are functions or objects that share data and behavior across the app. Alternatively, services are objects that are connected via dependency injection. 

Questions for senior Angular JS developers

What is $scope?

$scope is the link between the view and the controller. It’s also an object that connects to the app’s model. They provide APIs to monitor changes in the module and send all changes from controllers, services, and event handlers into the view. 

What is “transclude” and what is it used for?

It’s a directive that creates an insertion point for the transcluded (“marked”) DOM of the nearest parent directive that utilizes transclusion. Developers tell Angular.js to capture all inside that directive within the markup and use it somewhere else in the “marked” with ngTransclude part of the directive’s template. 

What is the $location service for?

The $location service parses the URL in the browser’s address bar and makes the URL available to the app.

This is a list of questions you can ask your future candidates — but it’s by no means ultimate or conclusive. It’s best to supply tech-related questions with product-related ones. This would give you a clear picture of whether your future employee can connect their tech knowledge to product development & solving business problems.

Soft Skills Assessment for Freelance Angular.js Developers

The below topics are what will help you get a read on whether the person’s soft skills would fit your project. 

• What was your favorite web development project and why you liked working on it 
• Do you prefer working in a team or solo?
• What are the main challenges of working remotely for you?
• How do you react to negative feedback?
• Can you work efficiently without supervision?

Angular.js Developer Salary Rates

To hire AngularJS programmers you should be ready for, on average, $60,528 yearly wages — but that changes depending on the region and model of working.  

The average developer income depends on the following conditions:

• Experience and position. In America, the salary of a junior starts from $2000 a month, and a senior Angular js developer who can create reliable web solutions on their own can receive more than 4.5-5 thousand dollars.
• Location & collaboration type. In-house coders earn the most in megacities of Europe and America. In Eastern Europe, North Africa, and South Asia, developers ask for lower rates. Freelancers ask for less than people who work in-house. 
• Industry. AngularJS with in-depth domain expertise will generally ask for a bigger salary, especially specialists from industries that work with sensitive data and heavy computation tasks. 

Also, there are hourly rates. The rates charged by AngularJS developers range from $10 to $100 per hour, with the average rate ranging from $40 to $50 per hour. Some engineers don’t bill by the hour, which is why some skilled developers offer project-based pricing based on their understanding of the app’s requirements.
