Product Badges – Limited Stock – based on all variant inventory

This script will show a badge for Limited Stock if all the variants are 3 or less. Change {% if total < 4 %} to the number being checked. How it works:

1. Checks to see if inventory is managed by shopify
2. Checks to see if there are product variants
3. Loops and captures an array of all the variant inventory
4. Loops and captures true or false statements for each variant checking to see if it is 3 and below
5. Creates another array for true and false statements
6. If the second array contains  false then badge won't show
7. For badge to show all true needs to return aka all inventory 3 and below
8. Else if product doesn't have variants just checks to see if inventory is 3 and below
