- In conclusion
A year later, Microsoft introduced the first version of Internet Explorer and rewrote Netscape’s interpreter for JS and named it JScript. It provided the initial support for HTML and CSS that allowed web developers to create dynamic web pages. However, there appeared a problem. HTML and CSS were different from the Netscape analogs, but the interpreter’s logic was the same, which led to the fact that most pages were displayed normally only in one of the browsers.
Let’s discover its main characteristics. JS is a high-level language that is considered multi-paradigm, which means that it supports different types of programming, such as functional or event-driven. One of the main peculiarities is its dynamic typing that leads to more freedom in the development process and prevents the code from being critically overloaded with the types of variables. However, dynamic typing has certain limitations that we’ll discuss later.
Primarily, it was designed for client-side implementation, but later, Microsoft added engines that allow running the script on the server and displaying it according to the user’s browser.
JS has a somewhat complicated code structure. It is not problematic in small and medium applications, but the code becomes quite difficult to maintain and reuse when it comes to enterprise development.
WHAT IS TYPESCRIPT
Described peculiarities make TypeScript suitable for writing clear code not only for front-end in web applications but also for server-side, unlike its competitor, JS. While other JS supersets like CoffeeScript make the script more understandable for people, TS aims at making the code clear primarily for the interpreter.
Is TypeScript easy to learn?

TypeScript is not limited to one particular option. It supports both static and dynamic typing. It is extremely useful because dynamic typing may still be a good option for some specific tasks. Static typing, in turn, makes the code more structured and increases the performance due to the absence of run-time errors. It also results in better documentation, which other developers working on the project would appreciate.
It is difficult to answer the question, whether JS and TS are object-oriented languages. Of course, they both support some OOP principles, but developers don’t necessarily have to follow them, unlike in the case of some pure OOP languages like C# or Java.
The situation with TypeScript is quite similar. Unlike JS, it is class-based. It supports all main OOP principles but works perfectly without them, which is why TypeScript still cannot be named a pure object-oriented language.
Thus, none of these technologies are object-oriented despite that they support this option. Instead, both TS and JS are multi-paradigm languages that allow developers to choose the approach according to the situation.
Optimal Project Size
In addition, modern IDEs provide high-quality refactoring in the case of object-oriented languages, which, again, makes the code more structured and understandable. Also, as we’ve already mentioned, bugs are detected faster in TS due to the compilation, and run-time errors are a very rare thing.
No wonder that there are so many reasons for “Why use TypeScript for large projects” because it was designed for them.
Why Use Typescript
Now, when we’re familiar with what is TypeScript and its main technical features, let’s name its specific pros and cons.
It has such upsides:
- Possibility to use JS libraries. Apart from the fact that TS is syntactically based on JS, which leads to a very smooth learning curve and easy transition to this language, it supports all JS libraries
- Constant improvements. TypeScript pays much attention to always being up-to-date and providing developers with the most modern features. ECMAScript is constantly developing and implementing new features that can enhance the coding process. For example, recently, it introduced private classes that lead to higher code security.
Why are TypeScript advantages?
Among the TypeScript upsides, there are static typing and a well-supported OOP approach that lead to easy refactoring in modern IDEs. Also, it is possible to use all JS libraries and detect bugs at the very early stages.
OUR EXPERIENCE WITH TYPESCRIPT
Waste Recycling Workflow Building App
It is an application built for the waste and recycling industry. It may be used not only by the recycling companies themselves but also by plant builders, system integration companies, consultants, and engineering offices.
Waste recycling workflow building app provides such features:
- Design (modeling) of the sorting processes
- Testing recovery and recycling operations. This feature allows specialists to input the data about different materials, set up particular scenarios, and see how they will be managed. It also allows using the saved ones to perform the analysis or comparison
- Analysis and optimization. On the basis of data gathered for testing along with the actual calculations, the system helps to optimize the commercial performance and adjust the prices according to the ones on the market. It also allows choosing the best strategy of recycling and predicting the expected outcome.
- Sharing. Specialists working on a particular project can give access to other team members or share the formed diagrams with the people from other teams in order to let them contribute their knowledge about the process.
The screenshot below demonstrates a part of what can be done with the help of the waste recycling workflow building app.
It may look like the diagram creation similar to draw.io at the first glance. In fact, the building of the waste recycling process involves complex calculations that are happening on the backend in real-time to provide the user with dynamic information about the output of the workflow. TypeScript greatly helped us in the implementation of this sophisticated feature.
As you can see, there’s a section where you can input configurations and parameters, and on their basis, the system will generate a virtual process of material utilization and recovery. The percentage of recovered or utilized materials varies depending on numerous factors, such as its quantity, various ratios, or at what point the material has been added to the processing machine. Later, the application forms the reports and can give some advice on better recycling.
Let’s look at the other application and see what it has in common with the described one, and why we chose exactly TypeScript for both projects.
An HR Solution For A Talent Management Company
The second project is an HR management system for a talent management consulting company. The academy provides human resources management services for other companies. To do with the maximum efficiency, they need an application that will help keep everything under control, analyze the data, and optimize the process.
To be more specific, let’s see what HR services look like. Our client usually follows such steps while performing the work:
- Interviewing a candidate
- Forming his profile
- Forming a profile of the desired candidate for a particular job
- Comparing the desired profile with the one of an actual person
- Forming reports about the candidates
- Sending the results to the client
Long ago, it was done manually, but now, when you need to do everything quickly in order to stay competitive, it’s essential to maximize the effectiveness of the working process and deliver results as fast as possible. Our solution helped them achieve it.
The system has two main features: reporting and administration. It calculates the percentage of the maximum possible leadership competencies, compares it with the candidate’s results, and, according to particular criteria, defines whether a person is suitable for the job.
On the basis of received data, the system forms diagrams that visually represent the level of the candidate’s efficiency due to the various criteria and how it correlates with the desired capability.
The visual representation allows a simple understanding of a person’s development vector. For example, in the screenshot below, you can see a diagram that shows four areas of work capabilities. The darker shape shows the desired targets, and the lighter shape is the actual candidate’s results.
The main system’s goal is to simply visualize the results of the candidates’ interviews, show their upsides and drawbacks, so the client can decide whether they want to employ the person or not.
Considering that the sorting and HR management solutions are big projects, most likely, many developers would work on the code. Imagine how many questions a developer would have if he received a part of code with many variables with unknown types. It would take him to examine the whole code in order to understand where and when variables would be used, what operations will be performed with them, etc.
The development time with TypeScript saves about 20% of time leading to 20% of the budget economy. To be more specific, let’s see why coding in TypeScript is less time-consuming. Modern TypeScript IDEs allow dividing the code into smaller parts. For example, enums, which are a list of constants, are stored in separate files. Thus, it enables very quick code editing. Methods can also be grouped and stored separately, resulting in easy and fast access to each part of the code. It makes the code much more clear and takes developers less time to get to the bottom of the code written by the previous developer.
