I'm not new to react, but im new using hooks, today I was playing with an array of selected elements and selection/unselection.

If they are selected then one icon is shown, if not, another icon (I just change the name prop, not the component itself.

The console.log I do every render shows the right results, but it is not working as expected on the JSX.

The render seems to only reload (Show the right icon) when I unselect. Explaining as a list the procedure and my problem:

1. All elements come selected
2. I unselect one element (remove from list), the icon changes.
3. I select back the element (add to list), the icon don't change.
4. I unselect another element, then it works and the components are reloaded

Here is my object array:

I am making a python game with pygame on my home computer for school running with python 3.6.3 and pygame 1.9.3. When working on my game I also worked at school where it was working correctly just slower as expected but when I started to load images it randomly choose the images and didn't load the correct ones on school computer not home one (I think this might be due to change in arrays and loading them). I soon found I was running python 3.5.3 at school and then when updating it the python and pygame, The game ran extremely slow and was unplayable. The images loaded correctly but the change in speed was extreme.

Summary:

Pygame at home working great pygame 1.9.3 python 3.6.3. Working fine at school until loading images python 3.5.3. Updating school corrected it but is now running unbearably slow.

I would love a fix for this problem either working for other python version or running at a variable speed for school computers. If there is any optimisation that could be easily implemented that would be very useful as well as I am not sure how to load images effectively

Code:

import pygame import random import math

here is my code,

Detail: i have 2 divs, and when i click on (first link) so (first detail) open. then i click on (second link) so (second detail) open. and now i need that when i click on (first link) so add class active in first link, and when i click on (second link) and now (first link) active class remove and added the active class (second link). and when i again click on (second link) then active class remove.

This is the code where i click. i need to add "Active" class in Tag. through jQuery. how can i add in jquery?
