LOOPS

HookScript has a single loop statement starting with the for keyword, following your condition and a colon ( : ). The colon starts a new block with its own scope for declaring variables local to that block. All for statements are terminated with the end keyword.

For loop

For general looping, the for loop uses a conditional statement to determine when to stop looping

var x = 0
for x < 10:
	x++
end
print(x)

For-of loop

For looping over an iterable (e.g., a list) you can use the of keyword. You must specify the variable name to hold the value for each iteration. In the example below, we use the variable name el, but you can choose whichever name you like. The variable will be automatically scoped to the loop's block.

var myList = [10, 20, 30]
var total = 0
for el of myList:
	total += el
end

Iterable types include:

• list: each iteration returns the next value held in the list
• dict: each iteration returns the next property value held in the dict (order is not guaranteed)
• record: each iteration returns the next field value held in the record
• text: each iteration returns the next character
• table: each iteration returns the next record of the table
