🧐 Question
Medium Custom WordPress Shortcode Shortcodes	Solve
You're creating a custom WordPress shortcode that users can insert into their posts and pages to display a promotional banner. Your initial PHP code is as follows: A user inserts your shortcode into a post like this: However, when the user previews the post, the content inside the `[promo-banner]` shortcode isn't displayed. Instead, the user sees the shortcode itself. What change can you make to fix this issue? A: Replace `'promo-banner'` with `'[promo-banner]'` in the `add_shortcode` function. B: Replace `'promo-banner'` with `'[promo-banner]'` in the shortcode inserted into the post. C: Change the `promo_banner_shortcode` function to accept only one parameter. D: Use `do_shortcode` function to process the `$content` inside the `promo_banner_shortcode` function. E: Replace `$content` with `$atts['content']` in the `promo_banner_shortcode` function.
Medium Iteration in WordPress Plugin Asynchronous JavaScript	Solve
You're developing a WordPress plugin where you need to fetch comments for a list of posts from a WordPress database using AJAX. The JavaScript code is as follows: The processComments function processes the comments for other operations and is working as expected. However, when running the code, you notice that the console logs for fetched comments don't appear in the order of the post IDs. Instead, the logs appear in a seemingly random order each time. What change can you make to ensure the comments are fetched and processed in the order of the post IDs? A: Use a traditional for loop instead of forEach. B: Use setTimeout to delay the execution of fetchComments. C: Use sort on postIDs before calling forEach. D: Change forEach to map and use Promise.all. E: Make processComments function asynchronous and await it in the forEach loop.
Medium Responsive load Optimization	Solve
Here’s the code snippet of interest from a client's WordPress code: You are reviewing the client's code and have to make recommendations to improve speed of the WordPress site. Which of these are good recommendations? A: Cache the website to improve the site but need to move the responsive logic to CSS. The conditional logic might not be cached if the cache provider does not trigger the conditionals B: Cache the website to improve the site. No need to move the responsive logic to CSS C: jQuery is very commonly loaded on live sites multiple times due to poorly written plugins/themes. Ensure required JS files are enqueued only once and when they are needed D: CSS in <head> file will affect the speed of the site since the entire CSS file has to be loaded before rendering the site. It is advised to load only the CSS that is mandatory in the <head> and move the rest of the CSS to the later portions of the HTML
Medium Shortcode Development in WordPress Shortcodes WP_Query Loop	Solve
You're developing a WordPress plugin that provides a shortcode to display the latest posts. The shortcode is [latest-posts count="3"], where the "count" attribute determines the number of latest posts to display. Your initial PHP code is as follows: You test the shortcode on a page and find that the page content following the shortcode doesn't display. What change can you make to fix this issue? A: Use `return $query->have_posts();` instead of `$query->the_post();`. B: Use `wp_reset_query();` after the while loop. C: Use `the_content();` after the while loop. D: Use `wp_reset_postdata();` after the while loop. E: Use `return $output;` before the while loop.
Medium WP REST API REST API HTTP Requests JSON Response	Solve
You're developing a custom WordPress plugin to fetch and display a list of posts using the WordPress REST API. Your initial JavaScript code is as follows: This code works fine when the website URL is `http://localhost/wordpress`. However, when you move your website to a different domain (for example, `http://example.com`), the list of posts doesn't display. What change can you make to fix this issue? A: Replace `/wp-json/wp/v2/posts` with `http://example.com/wp-json/wp/v2/posts`. B: Replace `/wp-json/wp/v2/posts` with `http://localhost/wordpress/wp-json/wp/v2/posts`. C: Use `wp_localize_script` to pass the website URL from PHP to JavaScript, and prepend it to `/wp-json/wp/v2/posts`. D: Use `admin_url('admin-ajax.php')` to replace `/wp-json/wp/v2/posts`. E: Use `site_url('/wp-json/wp/v2/posts')` to replace `/wp-json/wp/v2/posts`.
Easy Background Properties	Solve

Medium Async Await Promises Promises Async-Await	Solve
What will the following code output? A: 24 after 5 seconds and after another 5 seconds, another 24 B: 24 followed by another 24 immediately C: 24 immediately and another 24 after 5 seconds D: After 5 seconds, 24 and 24 E: Undefined F: NaN G: None of these

Easy Registration Queue Logic Queues	Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10
Medium Visitors Count Strings Logic	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.
