A smarter approach would be to write a function that uses many conditional statements to return incremental values based on different numerical ranges

I'm trying to write a function that returns a specific value if the input is within a certain range of numbers. Normally, I would write a series of if/elseif statements to accomplish this task. However, I'm dealing with a large number of ranges, so writing out 30+ if/elseif statements seems inefficient. Let's say I have a minimum and maximum number for an overall range, and I want to split it into smaller ranges. For each range I want to return some values. Ideally, the return value for each range would be decremented by some fixed number. To provide context, I'm trying to use something like this

Use useState to set the value entered in the form

I'm trying to use useState to set the value of an input, but it's not working the way I want it to. So I used Formik to create a weekly schedule for an appointment system. I have a radio button for free appointments. When selected, I get the time data for the appointment. But I didn't get this day. So I tried adding another input to get daily data. I set the entered value to the state. When the radio button is selected it sets the date. But onSubmit I get the initial value, not the newly set value. Interestingly, when I try to write something in the input,

Vue Js v-model on v-select shows wrong value

There is some kind of bug on my v-select that causes v-model to display a different value than the actual value of the variable.

How to handle potentially "false" inputs in JSON? Discussion of alternatives

Let's say, I'm not sure if the selected authorities exist (but if they exist, I want them to be selected). If there are no selected authorities, I want jQuery to select the authorities regardless of whether they are selected (actually, this means retrieving the value of the hidden input). My idea of using JS's "true value"/"false value" concept to handle this situation is: letuser={id:$(this).find('[name=id]').val(),username :$(thi
