Product.js

// I think we should create 2 entries for same product one in english and another in spanish

// For example: Product is IphoneX,

// Save one entry in english Language

{
  name: "IphoneX",
  price: x,
  lang: "en",
  public_id: 123
}

// Save another entry in spanish Language

{
  name: "IphoneX in spanish",
  price: x,
  lang: "es",
  public_id: 123
}

// By this we can easliy query data 
// For eg if we need IphoneX in es launguage
  findOne({public_id: 123, lang: es})
