QUESTION
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.
My code is as follows:

QUESTION
I tried to use better-docs plugin for jsDoc to make documentation for my react.js project through this link: https://medium.com/@wojciechkrysiak/document-reactjs-components-with-preview-by-using-jsdoc-70d39d2cc777.
When i run bellow command to create my docs:
...ANSWER
Answered 2020-Jan-22 at 11:26I had a similar issue. Basically, the problem is that the path module puts "\" in paths for Windows instead of "/" which causes paths to break.
The file entry.js is created by bundler.js which can be found in node_modules/better-docs/bundler.js This is the file that puts the wrong paths in entry.js. To fix this, I manually replaced the "\" with "/" in multiple places in the bundler.js file by adding .replace(/\\/g,"/") when paths are created.
How I changed the bundler.js file (just look for all the .replace(/\\/g,"/") to see where you need to add them):
QUESTION
I've just started to learn ReactJS (with only basic knowledge of HTML/CSS/js) and I would like to build a site creates pictures dynamically from a JSON file which contains an image source, title, description, and href.
I am 100% sure that there are numerous and probably lacking all sorts of basic knowledge about how this works, so I apologize and appreciate your time and help.
Before trying to use react, I implemented it using only basic HTML/CSS/js, with a js function which looped through and insertAdjacentHtml'd it into a target div, here (warning, very slow and unoptimized - runs long scripts 170x). Now I'm trying to adapt it to react to get a sense of how it would work using components.
my plan so far I made an app.js which I can npm start at which looks like the following. I created a container which I intend on using to hold all of the pictures. I believe I have 3 major problems (and knowledge gaps) at this moment.
1) I think one big problem for me here, is I have had a difficult time understanding how the components can get created and inserted into the app.js. In regular JS, it was easy to picture that the HTML was getting changed with every loop. Using react, I read tutorials which suggested using a map function to go through the JSON array, and at every loop create a component to be rendered. I'm sure that there's probably something wrong here already.

Webpack config is found under
...ANSWER
Answered 2017-Feb-28 at 15:17NOTE: The process I went through to answer this question is not longer necessary, as the Rails team has moved JavaScript dependencies back into the root of the project by default.
This answer is a two-parter. First, I'll explain how, after much blood, sweat and tears, I arrived at my current Webpacker + React + Jest test environment. Second, I'll dive into why all the expenditure of the bodily fluids.
Part 1: ImplementationRails. I generated a new Rails app, skipping all of the things that I'm not likely to need.
