What is the reasoning behind defaultValue possessing the type of any in TextField Material UI?

According to the Material UI guidelines, the component TextField specifies that its defaultValue property accepts the type any. I decided to experiment with this a bit and found that in practice, defaultValue actually supports multiple types. You can see my test here: https://codesandbox.io/s/awesome-benz-7vj06. This discrepancy has led me to question the logic behind defining defaultValue as having the type any.

Answer №1

Perhaps the reason for this is that assigning defaultValue to values like: string, number, undefined, null, and array, which would then be converted using the toString method, is considered normal. Therefore, it might make more sense to use type any instead of specifying all these different types.
