In React ES6, why does the input field lose focus after typing a character?

Question

In my component below, the input field loses focus after typing a character. While using Chrome\'s Inspector, it looks like the whole form is being re-rendered instead of ju

Answer 1

it is because you are rendering the form in a function inside render().

Every time your state/prop change, the function returns a new form. it caused you to lose focus.

Try putting what's inside the function into your render directly.
