Strictly or !not operator.

Hi Jason

No you wont run in to issues here, you can do it either way. Remember though, that this is comparing against its falsy value

const field = document.querySelector("#info");
if (!field.value) {
   ...
}

and this is strictly checking equality.

const field = document.querySelector("#info");
if (field.value === null) {
   ...
}

Both of which have the same outcome. There is an error with your code though, if null both dont have a property value so you can completely remove that and keep it as just field, not field.value

Check out MDN docs and you will find a section called return value, this is how you know what to check for if you want to strictly check equality.

An HTMLElement object representing the first element in the document that matches the specified set of CSS selectors, or null is returned if there are no matches.

So for your case, if you find it easier to do strict equality, as stated with the MDN docs it will return either HTMLElement or null.

const field = document.querySelector("#info");
if (field === null) {
   ...
}

And if you refer the falsy way, there is no need to check null as a null value boolean is falsy

const field = document.querySelector("#info");
if (!field) {
   ...
}

Hope this helped clear things up

Have fun!
