Lviv is not only about history and architecture, cultural events and tourists, but is also one of the 3 largest IT hubs in Ukraine, alongside Kyiv and Kharkiv. In 2019 there were 416 tech companies, out of which more than 188 are registered on TechBehemoths. In addition to this, Lviv was listed among the 10 most cost-effective locations by Financial times, in 2019 and also, 4 IT companies from the top 100 best BPO, have offices in Lviv, according to an article shared by Lviv IT Cluster. 

Other advantages of Lviv as a tech center are the economic attractiveness, which makes the city a feasible destination with qualified professionals in the IT industry, such as web designers, developers, software engineers, and other specialists in related fields. 

Youngsters interested in the field of IT can always find specialization courses in different fields, and those professionals that feel insecure, have a place to retrain and improve their skills in Lviv. This means that the IT and tech academic background in the city is at one of the highest levels in the region. 

The city also has a positive development dynamic, and so, in the past 7 years, the number of investors and IT companies in Lviv significantly increased. The most important aspect when attracting new companies to a city is to keep them satisfied with the entire environment - a lesson that Lviv accomplished. 90% of all CEOs of local IT companies are satisfied with the city, and 83% will continue to invest. On the other hand, local companies that open offices in Lviv, export IT services abroad. Web agencies, digital companies, and professionals working for Lviv-based IT companies are attracting more new clients each year. 

In 2019 there were more than 25K professionals enrolled in the IT sector in Lviv, but in 2021 there could be more. With an average salary of $1866/mo according to IT cluster and $2800/mo according to Glassdoor, the number of IT specialists increased by more than 85% in the past 2 years.

Overall, Lviv is expected to increase its IT capabilities and deliver more IT services and service types in the near future. With a new generation coming up, companies located there are able to assimilate and produce valuable digital products and technologies. 

Angular (formerly AngularJS) is a popular open-source web application framework maintained by Google and a community of developers. It's used for building dynamic, single-page web applications (SPAs) and web-based applications in general. Angular provides a structured and organized way to create complex web applications by extending HTML with additional features and enabling the development of interactive, responsive, and maintainable front-end web interfaces. Here are some key aspects and concepts of Angular:

1. Component-Based Architecture

2. Templates 

3. Directives

4. Dependency Injection

5. Services

6. Routing

7. Observable and RxJS

8. Modules

9. Testing

10. Cross-Platform

Angular's structured approach, strong tooling, and vibrant ecosystem of libraries and extensions make it a powerful framework for building modern web applications. It is particularly well-suited for large and complex projects where maintainability and scalability are crucial.

Companies may choose Angular over other front-end frameworks for their projects for a variety of reasons, depending on their specific needs and priorities.

• Google Backing: Angular is developed and maintained by Google. This association often gives companies confidence in its long-term support, stability, and continuous improvement. Google's involvement is seen as a sign of reliability and commitment to the framework.

• Mature and Established: Angular has been around for a while and has a strong track record of being used successfully in large-scale enterprise projects. It has a well-defined architecture and best practices, which can be beneficial for maintaining and scaling applications over time.

• TypeScript Support: Angular is built with TypeScript, a statically-typed superset of JavaScript. TypeScript provides better tooling, code maintainability, and catches errors at compile time, which can reduce bugs and enhance code quality, making it attractive to companies that prioritize robust code.

• Full-Featured Framework: Angular provides a comprehensive set of tools, libraries, and features out of the box, including routing, form handling, HTTP client, and more. This can save development time and effort compared to integrating multiple third-party libraries in other frameworks.

• Two-Way Data Binding: Angular offers powerful two-way data binding, which allows for automatic synchronization between the data model and the view. This feature can make it easier to develop interactive and responsive user interfaces.

• Large and Active Community: Angular has a large and active community of developers and a wealth of resources, including documentation, tutorials, and third-party libraries. This can be beneficial for finding solutions to common problems and getting support when needed.

• Enterprise-Ready: Angular provides features like dependency injection, modularity through modules, and a strong emphasis on testability. These characteristics are well-suited for building robust and maintainable enterprise-level applications.

• Strict Coding Standards: Angular enforces a set of coding standards and best practices, which can lead to more consistent and readable code. This can be important for companies with multiple developers working on the same codebase.

• Cross-Platform Development: Angular can be used for building both web and mobile applications. Companies looking to develop applications for multiple platforms may choose Angular for its ability to share code between web and mobile apps using technologies like NativeScript or Ionic.

• Integration with Backend Technologies: Angular can easily integrate with various backend technologies and APIs. This makes it suitable for projects where the front end needs to communicate with different types of server-side applications.

• Security Features: Angular provides built-in security mechanisms to help prevent common web vulnerabilities like Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF). This can be crucial for projects with high security requirements.

• Ecosystem and Tooling: Angular has a rich ecosystem of tools, extensions, and IDE support, including Angular CLI for project setup and management. This can streamline development workflows and improve productivity.

Ultimately, the choice of Angular or any other framework depends on the specific project requirements, the development team's expertise, and the company's long-term goals. Companies evaluate various factors to determine which framework aligns best with their needs, resources, and priorities.
