In a React project, I have the requirement of opening Modal from another component. I found suggested questions from StackOverflow but, not yet convinced. As I need to make the Modal component reusable across all components. See the code below for reference

I am using npm package vue-custom-range-slider but i have one problem my slider is divided into four colors blue, green, yellow, red it looks like this

Minimum number 19 and maximum number 65

Imagine that a person can choose a certain age blue color is a range from 19 to 21 green 22 to 30 yellow 31 to 49 and the last red is above 50 for a more understandable example you can see this picture

I used a linear-gradient to split the slider into four slider colors, Now let me explain the problem.

I need to make the numbers for the blue range, that is, the numbers from 19 to 21 are inside the blue, 22 - 30 are inside the green 31-49 are inside the yellow, and above 50 are inside the red

Because at the moment the numbers are set incorrectly at the moment, for example, the numbers for blue are set from 19 to 30 and so on with all

I recommend looking at this code in codesandbox for a better understanding.

After compiling I receive this error message:

Failed to compile src\App.js Line 4:1: 'state' is not defined no-undef

I have a very large array of objects and some of the objects have a nameless property. What is an efficient way to remove the property?

I want to enable and disable checkboxes based on two variables: 1) Is there already a checked count of 2+, 2) Is the current checkbox enabled or disabled. i.e. I have a list of items, and I want to limit the user to only selecting two out of (potentially) endless options.

I have a handleCheck() function, but I think by the time that's applied it's already too late to control the checked value of the checkbox, right? Because I can successfully call alert() after the user has checked their third box, but then the check appears anyway; I can't stop it from being checked. That's why I'd like to put the control inside the HTML: the checkbox will be disabled if the count is more than two and the user hasn't chosen this checkbox. In order to choose this checkbox, they'd have to deselect another.

What I essentially want to do is this:

disabled={count >= 2 && thisCheckbox.checked === false}

I'm using React to dynamically render checkbox + a whole load of data and visuals on a case-by-case basis, so it's not like all the checkboxes are in one neat form.

I've tried various SO threads but most of them use jQuery or do their handling in JS in the onChange function (handleCheck(), in my case), which is already too late because the check will still be applied (as far as I know).

EDIT

Here's a sandbox link with the basic set up: https://codesandbox.io/s/nameless-sun-3jsmn?file=/src/TestimonialsSettingsUnit.js

I am trying to have several objects on my page move around the center like a circle. I have found a codepen very similar to what I want, however I cannot replicate the method the author used. The method was:

I need to scrape a book web site and save the information (price, code, fees, etc.) in a CSV file as a table, but when I try to save the data in the CSV file, I have the title name repeated several times and the information is vertical, I need to place it horizontally and at the end of the information in a book, I need the next information to be on the bottom line.
