Godot - Getting the Sum of an Array

This code example shows how to get the sum of an array in GDScript.

Use `reduce()` to get the sum of an array.
It calls the specified Callable for each element in the array and accumulates the result.

var array = [5, 6, 7]

var sum = array.reduce(func(acc, num): return acc + num)

print(sum)
# 18
