Managing Multiple Inputs in React
Learn how to manage several input fields efficiently using a single state object and dynamic updates — the scalable way to handle real-world React forms.
We'll cover the following...
Most forms have more than one field — such as name, email, and password. Using separate useState hooks for every field works, but quickly becomes repetitive. Imagine a registration form with ten fields — you’d end up writing ten state variables and ten onChange handlers.
React provides a simpler way: represent all inputs as properties inside a single state object. Each field updates its corresponding property dynamically based on the input’s name attribute. This pattern keeps the code concise and scalable while maintaining React’s controlled component principle.
Using a single state object
By grouping all fields into one state object (for example, formData), we can:
Manage all input values from one place. ...
