A social media company, InstaConnect, is building a new feature to allow users to share their favourite quotes. The feature is developed using React and JavaScript. The development team is using ES6 features to write more efficient and concise code. The quote-sharing feature requires a function to concatenate the user's name with the quote text. The function should take two parameters, userName and quoteText, and return a string in the format "userName: quoteText". The team is using arrow functions to implement this functionality. However, the function is not working as expected, and the QA team is reporting issues with the concatenated string.

Here is the code snippet:

const generateQuote = (userName, quoteText) =>
 userName + : + quoteText;
What is the mistake in the above code snippet, and how can it be corrected?

A social media company, "SocialConnect", wants to develop a feature to display trending posts on their platform. They have a large dataset of posts and want to filter out the top 10 trending posts based on the number of likes. The development team has decided to use JavaScript for this task. They are using ES6 features to write efficient and concise code.

The team leader, Rachel, has written a function getTrendingPosts that takes an array of post objects as an argument and returns an array of the top 10 trending posts. The post object has properties like id, title, content, and likes. Rachel wants to use arrow functions to simplify the code.

Here is the code snippet:

const getTrendingPosts = (posts) => {
 // Sort the posts in descending order based on likes
 const sortedPosts = posts.sort((a, b) => b.likes - a.likes);
 
 // Filter out the top 10 trending posts
 const trendingPosts = sortedPosts.slice(0, 10);
 
 return trendingPosts;
};
What is wrong with this implementation?
