I have a multidimensional array, and I (finally) know I can subset it with a matrix, which has as many columns as there are dimensions in the array. But I need to skip a dimension in the process, to get/set not one element of that dimension, but all of them. How to?

I am doing an online Full Stack Web Developer Bootcamp and have just been introduced to React JS events and am having some difficulty implementing the following instructions:

The menu component should only display relevant items. For example, if the user is on the “shop” page, the “shop” menu item should no longer be displayed.

I have tried executing this via the "activeClassName" and CSS method, but this is unfortunately not recognized as a DOM property.

I have also tried following guides and previous Stack Overflow questions' answers that offer solutions such as this: https://www.pluralsight.com/guides/how-to-show-and-hide-reactjs-components

Unfortunately I have had no success as yet and would appreciate any assistance that anyone is willing to offer. It would be great to learn how to make use of this for future projects.

Fairly new to Python.... struggling with the for loop in my code, specifically the assignment of Key: 'topic_title'.

I keep receiving a "list index out of range" error. The JSON response at the "solicitation_topics" is nested so I believe I need to pass the index and this works when trying to access directly from the python terminal, however within the function I keep getting the error. Any help would be greatly appreciated.

I created a "slideshow" of images that change every 5 seconds using javascript. I would like to add a transition effect to change the opacity from 0.2 -> 0.8 using javascript. I don't think I fully understand how the transition property works.
