Cause: This error occurs when you try to access a property of an object that is undefined.

if (obj && obj.x) {
console.log(obj.x);
}Cause: This warning appears when rendering a list of components without unique keys.
Solution: Ensure that each child component in a list has a unique key prop.
{items.map(item => (
<ListItem key={item.id} {...item} />
))}Cause: This error occurs when the port you are trying to use is already in use by another process.
Solution: Change the port number in your application or stop the process using that port.
const PORT = process.env.PORT || 3001; // Change to a different port if neededCause: This error can occur if there is a syntax issue in your CSS file.
Solution: Check your CSS for missing semicolons or brackets. Use a CSS validator to help identify issues.
