Relatively new programmer here, don’t judge too hard
Long story short, I’m trying to make a password strength test for a project, but I figured I won’t be able to get anywhere if I cant take an input on click and then put it into my function to then test it and send it back.
But I got stumped on basically the first step.
My goal as of right now to get the train rolling, is to be able to click the button, and then have the big strength text in the middle change to "it worked" or something like that, to find a way to call the function and use it properly.
(FYI, I was making a password generator as well for like a two in one deal, thats why theres an extra button and the css file has some "redundant" code)
Any help is massively appreciated <3

To make your code work change this line:
let strength = "it worked"
to:
strength.innerHTML = "it worked"
To change the content of an html element you need to set the .innerHTML or .innerText property. Or if it is a form control, like an input or a select, then you would set the .value. And since you’ve set the ID of the element to strength you can use that to reference the element. And strength.innerHTML = "It worked!" will then change what appears on the screen.
Run the snippet to see how it works.
function PasswordTest() {
document.getElementById("strength")
strength.innerHTML = "it worked"
// return strength; <-- not required
}<input type="text" class="password" placeholder="password" id="password">
<h1 id="strength">Strength</h1>
<button type="button" class="button" onclick="PasswordTest()" id="btn">Check Strength</button>
