Is 'frontend' (one word) acceptable?

In informal tech contexts, 'frontend' is common. However, for clarity and formal writing, the hyphenated form 'front-end' is recommended, especially when used as an adjective (e.g., front-end development).

What's the main difference between front-end and back-end development?

Front-end development involves everything the user interacts with directly (visual design, layout, interactivity). Back-end development involves server-side logic, databases, and application infrastructure that the user doesn't see.

Can 'front-end' be used outside of computing?

Yes. It can metaphorically refer to the customer-facing part of any operation, such as retail (the shop floor), a business (the sales team), or a service (the reception desk).

Is a UX designer a front-end developer?

Not necessarily. A UX (User Experience) designer focuses on research, usability, and the overall feel of the product. A front-end developer is an engineer who builds the functional, interactive part of the interface based on designs. The roles often collaborate closely.

Common Pitfalls

Translation Traps (for Russian speakers)

Avoid direct calques like 'передний конец'. In computing, use 'фронтенд' (borrowed) or 'клиентская часть'. In business, 'публичная часть' or 'интерфейс'.

Common Mistakes

Using 'frontend' as one word in formal writing (hyphen preferred).
Confusing 'front-end' with 'user experience' (UX). Front-end is the implementation; UX is the feeling.
Using it as a verb (e.g., 'I will front-end the project' is non-standard).
