Explain this code to me in depth like every bit of it, like also what is useref. im talkin bout all the code babes import { useEffect } from "react"; import { useNavigate } from "react-router-dom"; function useUpdateEffect(effect, dependencies = []) { const isFirstRender = React.useRef(true); useEffect(() => { if (isFirstRender.current) { isFirstRender.current = false; } else { return effect(); } }, dependencies); } export default function useUniversalEffect(effect, dependencies = []) { const navigate = useNavigate(); useUpdateEffect(() => { effect(); }, [navigate, ...dependencies]); }
This block of code is a custom React hook called useUniversalEffect. It has two parameters, effect and dependencies which are callbacks that get executed inside the hook.
The first import in the code is useEffect from the "react" package which is used to update state based on some condition. The next import is useNavigate from "react-router-dom" package, which is a hook that provides a way to navigate declaratively to any location in the application defined by the props of the component.
The function useUpdateEffect is a custom React hook that is used within the useUniversalEffect hook. It's used to run an effect on component updates, but not on initial render. This custom hook takes two parameters: effect and dependencies, where effect is the effect that needs to be run and dependencies is an array of values that the hook needs to monitor. If dependencies are not provided, the hook default to an empty array.
Within the useUpdateEffect function, the React.useRef() method is used to set the isFirstRender variable as a true boolean value for the first time and it is not updated unless the component re-renders. When the component re-renders, the useEffect function is triggered. If it's the first render of the component, the value of the isFirstRender is set to false. If it's not the first render, it will return the effect
Finally, the useUniversalEffect function definition is using the useUpdateEffect function, and it takes two parameters: effect and dependencies. effect is the effect that needs to be run while dependencies is an array containing all the dependencies required for the defined effect. The navigate method provided by the useNavigate hook and dependencies are included in the array of dependencies.
This custom hook useUniversalEffect will execute the effect on initial render as well as on every dependency list for any location change made by the user.

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. 👩💻🤝💻
