Why is text an input.value and not input.textContent

Shouldn't the text be an input.textContent because we are looking at the text, why is it a value instead?

Okay, so textContent and value are different things.

All nodes have a textContent property representing it's content and that of it's descendants. This will return null or an empty string for some types of elements, including input. input elements have a value property representing the element's initial data or the data provided by the user.

Try using a console.log on different types of elements to experiment with these differences. If you have any follow up questions, just let me know. Happy coding!

I tried something like this in the console, and I got undefined when I asked the console to show the value, but it worked when I asked the console to show the text content. This is what I got from the console:

Console was cleared
undefined
const test = document.createElement('p');
undefined
test.textContent = "hi";
"hi"
console.log(test.textContent);

undefined
console.log(test.value);
head_vendor-6a3288bb3aef100cad5d3497f90343103ec0f44b56f4ab0a057922302e7e77bb.js:1404 undefined
undefined

So, that is to be expected. value is an attribute specific to input elements. So while the p element has a textContent attribute, it does not have a value attribute.
