I have an array:
{ExpertiseId: "1Y", ExpertiseName: "Ad-Based Monetization", ExpertiseSubCategory: "Content & Information Services"},
{ExpertiseId: "2", ExpertiseName: "Balance sheet businesses", ExpertiseSubCategory: null},
{ExpertiseId: "3", ExpertiseName: "Brand Franchiser or Licenser", ExpertiseSubCategory: "Consumer Brands or IP"},
{ExpertiseId: "4", ExpertiseName: "Branded retail", ExpertiseSubCategory: null},
{ExpertiseId: "5", ExpertiseName: "Wholesale", ExpertiseSubCategory: "Consumer Brands or IP"}
How can I sort it by alphabetical order on ExpertiseSubCategory
