global

Currently in PineScript you cannot modify global variables in functions because of scope limitations.
One way to work around that is to use arrays.
This Library simplifies the use of arrays as global variables to make your code look cleaner.
If you're coming from other programming languages, I'm sure you will come across this issue in your PineScript journey at some point.

------------------------------------
The code below will throw an error that says: Cannot modify global variable 'price' in function.
var price = 0.0
function() =>
price := 5.5

------------------------------------
To work around that you can do:
var price = array.new_float(1, 0.0)
function() =>
array.set(price, 0, 5.5)

But that code does not spark joy.
------------------------------------
So I bring to you the global library:
import marspumpkin/global/1
var price = global.init(0.0)
function() =>
global.set(price, 5.5)
