how can I make my like button have one like per device
To make a like button have one like per device, you'll need to use some form of device fingerprinting. A device fingerprint is a unique identifier that can be generated from device characteristics, such as the user agent string, screen resolution, and installed fonts, among others.
You can use a library like fingerprintjs2 to generate a device fingerprint in JavaScript. Once you have the fingerprint, you can store it in a cookie or localStorage and check it when the user clicks the like button. If the fingerprint is already stored, you can prevent the user from liking again.
Here's some code using fingerprintjs2:
javascript Copy code
// Load the fingerprintjs2 library
const Fingerprint2 = require('fingerprintjs2');
// Generate the device fingerprint
const fingerprint = new Promise(resolve => {
Fingerprint2.get(function(components) {
const values = components.map(component => component.value);
const fingerprint = Fingerprint2.x64hash128(values.join(''), 31);
resolve(fingerprint);
});
});
// When the like button is clicked, check if the fingerprint is already stored
const likeButton = document.querySelector('#like-button');
likeButton.addEventListener('click', async () => {
const fingerprintValue = await fingerprint;
if (localStorage.getItem('fingerprint') === fingerprintValue) {
alert('You can only like once per device!');
} else {
// Do the liking action
localStorage.setItem('fingerprint', fingerprintValue);
}
});
Keep in mind that device fingerprinting is not foolproof and can be circumvented in some cases, such as when users clear their cookies or use browser extensions that modify their user agent string.

AI stands for Artificial Intelligence. AI bots are able to learn from conversations with users and expand their knowledge this way.
SheCodes Athena will help you with technical questions about your code using artificial intelligence to find the answer. Imagine a super powerful human who has memorized everything on the internet and can access that knowledge in a matter of seconds. 🤯
SheCodes Athena can answer most coding-related questions, even complicated ones! It can even find bugs in your code and tell you how to fix them in just a few seconds. Impressive, right?
Just remember we're still in testing mode so the AI may return strange or incorrect replies. Feel free to message us if this happens!
SheCodes Athena can only reply to coding-related technical questions. The same type of questions you would ask in the channels on Slack.
For questions that are not coding-related, write us here 😃
You should treat Athena like a SheCodes team member, so always be polite! 😊 Ask your questions as detailed as possible, just like you would do on Slack.
Here are some examples:
- Prettier isn't working on my VS Code. How do I fix this?
- How do I make bullet points with different colors using the list element?
- My code in Codesandbox is having some issues. Can you please tell me what the issue is? [Include the link to your Codesandbox]
For now, SheCodes Athena is limited to 5 questions per day for each student.
In that case, you can either ask SheCodes Athena a follow-up question, or you can post on the designated weekly channel on Slack!
Our technical assistants are still available on Slack and are always happy to help! 😍💪
Remember, questions are limited to 1000 characters.
- If you're working with an HTML file: Post a snippet of your code related to the issue you're having (just copy the code and paste it into the question box).
- If you're working with Codesandbox: Good news, you can just post the link to your Codesandbox and the AI Assistant will be able to view your code.
- If you have a longer question that would require an entire HTML file or more than 1000 characters, post it in the designated weekly channels on Slack! 😃
Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! 😍
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
