    const seasons = {
      SUMMER: {
        BEGINNING: "summer.beginning",
        ENDING: "summer.ending"
      WINTER: "winter",
      SPRING: "spring",
      AUTUMN: "autumn"
    let season = seasons.SUMMER.BEGINNING;
    if (!season) {
      throw new Error("Season is not defined");
    switch (season) {
      case seasons.SUMMER.BEGINNING:
      // Do something for summer beginning
      case seasons.SUMMER.ENDING:
      // Do something for summer ending
      case seasons.SUMMER:
      // This will work if season = seasons.SUMMER
      // Do something for summer (generic)
      case seasons.WINTER:
      //Do something for winter
      case seasons.SPRING:
      //Do something for spring
      case seasons.AUTUMN:
      //Do something for autumn
