Як працювати з темою
Вивчайте не окремі слова, а сполуки: biased towards, take into account, result in, take over, at scale. Після biased вживається towards або against; у take into account важливий прийменник into. Trade-off означає компроміс між пріоритетами. Wrap one’s head around — неформальний вираз «розібратися»; business-wise позначає бізнес-погляд. Уточнення: HTML є мовою розмітки, CSS — мовою стилів. У завданнях на виправлення оцінюємо мовну форму, а не перетворюємо авторські думки про технології на універсальні правила.
Мета: Обґрунтовувати вибір технологій через бізнес-потреби й компроміси.
Читайте текст частинами. Спочатку визначте головну думку, потім перевірте значення термінів і сталих сполук у контексті. Пояснення подано українською; читання, приклади й відповіді на англомовні запитання залишаються англійською.

Topic: Tech Stack
First, let us define what is meant by a tech stack. A technology stack, or tech stack, is a set of tools and technologies that work together to deliver a digital product or service to end users. It typically includes programming languages, frameworks, databases, and libraries. A tech stack usually consists of two main parts: the client side and the server side, also known as the front end and the back end.
Choosing an appropriate tech stack is a critical decision that should be made before development begins. Selecting unsuitable tools or changing technologies halfway through the development process often results in internal disagreements, dissatisfied clients, and wasted time. For this reason, developers and companies must adopt a certain mindset when deciding on a tech stack.
Many developers rely on widely adopted technologies that are in high demand across the industry. However, developers are sometimes biased towards tools they personally enjoy, rather than those that best meet project needs. Successful teams learn to see things from a business perspective and evaluate technologies based on real-world impact. When making such decisions, multiple factors must be taken into account.
HTML is a markup language and CSS is a style sheet language; they are used to structure and style web content and are often the first technologies beginners work with. They are not necessarily trendy, but they reliably get the job done for many simple projects.
React is a widely used JavaScript library for building user interfaces. Node.js is a runtime environment commonly used for server-side communication. Together, these tools can support applications that perform efficiently at scale, even as user demand grows.
PostgreSQL is an open-source relational database management system that stores data in rows and columns. In contrast, MongoDB is often selected when non-relational data structures are required. Choosing the right database can significantly affect how quickly a product can be brought to market.
Before adopting a particular tech stack, developers must understand that programming decisions involve trade-offs. Speed and flexibility rarely improve simultaneously, and every decision involves a trade-off between competing priorities. In some cases, the goal may be to rush the product to market, accepting higher maintenance costs later.
Maintainability is another crucial factor. At some point, another developer may need to take over the project, so the codebase must be easy to understand. Overly complex solutions can make it difficult for others to wrap their head around the system, which is rarely sensible business-wise.
Cost is also a major concern. Developers may be required to explain the ratio between investment and return, or even do the math to show how a chosen solution saves money or generates revenue over time.
When discussing personal projects with potential employers, developers should be able to clearly justify their choices. Rather than following trends, they should demonstrate informed decision-making and show how their solutions solved specific problems, increased productivity, and aligned with business objectives.
Ultimately, a well-chosen tech stack balances innovation and practicality. It supports growth, delivers value, and enables teams to move forward with confidence.
