In today's digital world, a user-friendly interface (UI) is no longer a luxury thing, it's a necessity.  Whether it's designing a website, a mobile app, or any other interactive product. A well-crafted UI can be the key to turning frustrated users into satisfied users.

This is where Nielsen's 10 Usability Heuristics come in. Created by Jakob Nielsen, a leading expert in web usability, these guidelines help designers create interfaces that are not only functional but also pleasant to use. Whether we are an experienced designer or just starting out, these principles can greatly improve the usability of our designs.

## What are Nielsen's Usability Heuristics?
Nielsen's usability heuristics are ten general rules for designing user interfaces. They are not specific instructions but rather broad tips to help identify usability problems. These heuristics provide a basic framework that can be applied to various platforms and devices, ensuring a consistent and effective user experience. Let's explore each of these heuristics and see how they contribute to better UI design.

### 1. Visibility of System Status
Users should always know what's happening through timely feedback. This means the system should keep users informed about what's going on, providing feedback quickly. For example, a loading indicator lets users know their action is being processed.

### 2. Match Between System and the Real World
The system should use language and concepts familiar to users, not technical jargon. It should follow real-world conventions, making information appear naturally. For example, using a trash can icon on delete action.

### 3. User Control and Freedom
Users often make mistakes and need a clear way to exit an unwanted state without a hassle. Support 'undo' action will give users the freedom to decide the actions they intended to do. This principle will helps prevent users from frustration and errors.

### 4. Consistency and Standards
Users shouldn't have to wonder if different words, situations, or actions mean the same thing. Consistency in design and terminology makes users feel more comfortable and familiar with the interface, reducing the learning curve. For example, we should use the same layout and button styles in different page.

### 5. Error Prevention
It's better to design in a way that prevents errors from happening in the first place than to rely on good error messages. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they proceed. For example, ask users to confirm their actions before finalizing it.

### 6. Recognition Rather Than Recall
Minimize the user's memory load by making options and information visible. Users shouldn't have to remember information from one part of the interface to another. Instructions should be visible or easily accessible whenever needed. This principle emphasizes designing interfaces that allow users to recognize options and information rather than recalling them from memory. For example, we provide description of the action and the konselor name that previously selected.

### 7. Flexibility and Efficiency of Use
Speed up interaction for expert users with shortcuts, without making it harder for beginners. For instance, we should make input fields that can perform shortcuts, such as copy and paste but still make the input field selectable for beginners

### 8. Aesthetic and Minimalist Design
Interfaces should not have irrelevant or rarely needed information. Every extra piece of information competes with the relevant information, reducing its visibility. A minimalist design approach ensures that only essential elements are present, reducing distractions and helping users focus on what matters.

### 9. Help Users Recognize, Diagnose, and Recover from Errors
Error messages should be in plain language, clearly indicating the problem and suggesting a solution. This principle is about providing clear and helpful error messages that guide users to fix issues effectively.

### 10. Help and Documentation
Even though it's best if the system can be used without help, it’s good to provide help and documentation. Such information should be easy to search, focused on the user's tasks, list clear steps, and be concise. Comprehensive and accessible help documentation ensures users can find assistance when needed, improving their overall experience.
