Could somebody help me, please?
With if-else condition works fine, but with these always the first block runs. I don't understand why.
let positiveNumber = -1;
positiveNumber > 0;
positiveNumber ? console.log('positive') : console.log('not positive');

You need to do the following for an if-else equivalent of what you are trying:
let positiveNumber = -1;
positiveNumber > 0 ? console.log('positive') : console.log('not positive');
This should give you back "not positive"

I have a js fn embedded in an aspx file. I reference a global code behind variable in the script. Works great. I moved the script to a .js file in the same project. OnClientcClick I find the script just fine but the variable is not available. Is it possible to reference or pass by value a variable to an external .js script?

It's not possible period. What was happening was the compiler was inserting your value into the js file during compile time or execution time.
Javascript executes on the client side and c# on the server. They are completely separate.
But no, I don't think you can do what you did before in a separate js file. And even if you can, my personal opinion is to never do it.

Thanks for the quick replay. I did do a goggle search half of the hits said you can the other half said no way. I did try a few examples but nothing worked. I don't do much in js but am curious as to why it would be a bad idea if it did work.

Because Javascript executes on the client side and C# executes on the server side. The 2 have no relationship to each other. They should not be mixed.
jQuery.ajax() is a very common way to get values from the server that are needed client side.

If you want help with some code then you need to show it as part of your question. People here are not going to go to some other website and try to analyse what you have done. Please edit your question and add the details there.

Thank you for your reply.
My code is a bit too long and I don't know which code snippet to include in here.
Can I close this message? I found the answer from somewhere else.

pseudocode is nothing more than a human description of an algorithm. You don't have to describe every single line of code, just the general idea of what's going on.
BUT! You DO have to understand what the code is doing and why. That part is up to you.

Post the code here so we can try it/check it for the problem that you say.
Reading the code on the images/screenshots is difficult, and is more difficult to debug it.

You probably need to talk to the owner of the git repository.

Hi, I need help on this question
"We want to know whether to order a particular candy. We should make an order if the total number in stock (inStock) is less than the weekly average sold (weeklyAverage).
Create a function called shouldWeOrderThisCandy that takes in
the inventory array
a specific type of candy (string)
The function should find the candy in the array that matches the name passed in.
When that candy is found, return true if the number inStock is less than the weeklyAverage. Otherwise return false.
If the array doesn't have any candy with that name, return false
This is what I have so far.
function shouldWeOrderThisCandy(inventory, string) {
for (let i = 0; i < inventory.length; i++) {
if (inventory[i] === string && inStock < weeklyAverage) {
return true;
} else {
return false;
}
}
return false
}
