# is​Option​Value​Combination​In​Encoded​Variant

Determines whether an option value combination is present in an encoded option value string.

`targetOptionValueCombination` - Indices of option values to look up in the encoded option value string. A partial set of indices may be passed to determine whether a node or any children is present. For example, if a product has 3 options, passing `[0]` will return true if any option value combination for the first option's option value is present in the encoded string.

## Props(**[targetOptionValueCombination](#props-propertydetail-targetoptionvaluecombination)**​,**[encodedVariantField](#props-propertydetail-encodedvariantfield)**​)

### Parameters

* **target​Option​Value​Combination**

  **number\[]**

  **required**

* **encoded​Variant​Field**

  **string**

  **required**

### Returns**boolean**

  ##### Description

  Check if option value is in encoding

  ##### JavaScript

  ```js
  import {isOptionValueCombinationInEncodedVariant} from '@shopify/hydrogen';

  // product.options = [
  //   {
  //     name: 'Color',
  //     optionValues: [
  //       {name: 'Red'},
  //       {name: 'Blue'},
  //       {name: 'Green'},
  //     ]
  //   },
  //   {
  //     name: 'Size',
  //     optionValues: [
  //       {name: 'S'},
  //       {name: 'M'},
  //       {name: 'L'},
  //     ]
  //   }
  // ]
  const encodedVariantExistence = 'v1_0:0-1,1:2,';

  // For reference: decoded encodedVariantExistence
  // {
  //   [0,0],    // Red, S
  //   [0,1],    // Red, M
  //   [1,2]     // Blue, L
  // }

  // Returns true since there are variants exist for [Red]
  isOptionValueCombinationInEncodedVariant([0], encodedVariantExistence); // true

  isOptionValueCombinationInEncodedVariant([0, 0], encodedVariantExistence); // true
  isOptionValueCombinationInEncodedVariant([0, 1], encodedVariantExistence); // true
  isOptionValueCombinationInEncodedVariant([0, 2], encodedVariantExistence); // false - no variant exist for [Red, L]

  // Returns true since there is a variant exist for [Blue]
  isOptionValueCombinationInEncodedVariant([1], encodedVariantExistence); // true

  isOptionValueCombinationInEncodedVariant([1, 0], encodedVariantExistence); // false - no variant exist for [Blue, S]
  isOptionValueCombinationInEncodedVariant([1, 1], encodedVariantExistence); // false - no variant exist for [Blue, M]
  isOptionValueCombinationInEncodedVariant([1, 2], encodedVariantExistence); // true

  // Returns false since there is no variant exist for [Green]
  isOptionValueCombinationInEncodedVariant([2], encodedVariantExistence); // false
  ```
