  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
  }

  Not how. forEach processes the array and performs some function for each value. In your case, it is not required to process all keys, but only one
