To simplify access to Liquid Objects it can be helpful to construct JS object to hold values

Doing this inside your product templates creates an object that you can fill with whatever information you want that pertains to the variants of your product:

  <script>
 var customVariantObject = {};
 ﹛% for var in product.variants %﹜
  customVariantObject[﹛﹛- var.id -﹜﹜] = {
    inventoryQuantity : ﹛﹛ var.inventory_quantity | default: 0 ﹜﹜,
    available : ﹛﹛ var.available ﹜﹜,
    inventoryManagement : “﹛﹛ var.inventory_management ﹜﹜”,
    inventoryPolicy : “﹛﹛ var.inventory_policy | default: “deny”﹜﹜”
  };
 ﹛% endfor %﹜
</script>﹛
