Type issue when finding pool pairs?

[trezm]

I've been using the BlockFrost adapter but noticed the code here, copied below and annotated for ease of reference:

  public async getV2PoolByPair(
    assetA: Asset,
    assetB: Asset
  ): Promise<PoolV2.State | null> {
    const [normalizedAssetA, normalizedAssetB] = normalizeAssets(
      Asset.toString(assetA),
      Asset.toString(assetB)
    ); // [string, string]
    const { pools: allPools } = await this.getAllV2Pools();
    return (
      allPools.find(
        (pool) =>
          pool.assetA /* Asset */ === normalizedAssetA /* string */ && pool.assetB /* Asset */ === normalizedAssetB /* string */
      ) ?? null
    );
  }

Is there some equality function or something that I'm missing here?
