| map(key0, value0, key1, value1, ...) | Creates a map with the given key/value pairs. | 
    
      | map_concat(map, ...) | Returns the union of all the given maps | 
    
      | map_contains_key(map, key) | Returns true if the map contains the key. | 
    
      | map_entries(map) | Returns an unordered array of all entries in the given map. | 
    
      | map_from_arrays(keys, values) | Creates a map with a pair of the given key/value arrays. All elements
      in keys should not be null | 
    
      | map_from_entries(arrayOfEntries) | Returns a map created from the given array of entries. | 
    
      | map_keys(map) | Returns an unordered array containing the keys of the map. | 
    
      | map_values(map) | Returns an unordered array containing the values of the map. | 
    
      | str_to_map(text[, pairDelim[, keyValueDelim]]) | Creates a map after splitting the text into key/value pairs using delimiters. Default delimiters are ',' for `pairDelim` and ':' for `keyValueDelim`. Both `pairDelim` and `keyValueDelim` are treated as regular expressions. |
