Go Collections is a Go (Golang) library that helps you work with and manipulate maps and arrays."

• Filter: Filters elements of a collection based on a given condition. It returns a new collection that contains only the elements that satisfy the condition.

  Example: You could use it to filter out even numbers from a collection of integers.

• ForEach: Iterates over each element in a collection and applies a provided function to it. This is typically used for performing actions on each item, like printing or updating values.

  Example: You can use it to print each element of a collection.

• GroupBy: Groups elements of a collection based on a specified key. It returns a map where each key corresponds to a group of elements that share that key.

  Example: Grouping a list of people by their city or age.

• Map: Transforms each element of the collection by applying a given function to each item, returning a new collection of transformed elements.

  Example: You can use it to square each number in a collection of integers.

• Zip: Combines two collections into a new one, pairing elements at the same index from each collection into tuples. If the collections are of unequal lengths, it will combine until the shortest collection is exhausted.

  Example: Combining a list of names with a list of ages into a list of name-age pairs.
