User Input Handling & Input Validation

User Input Handling & Input Validation

A. User Input Handling refers to the process of receiving, storing, and using user-entered information. It plays an important role in making applications interactive.

In this project, the value entered into the binary input field is captured using the onChange event and stored in the binary state. This ensures that the latest input is always available for validation and conversion.

B. Input Validation is the process of checking whether the entered data follows the expected format before it is processed. This helps prevent invalid or incomplete information from being used.

In this project, a Regular Expression (Regex) pattern, ^[01]+$, is used to verify that the input contains only 0s and 1s. The application also checks whether the input field is empty and displays an appropriate error message when necessary.
