Map Functions

Education is not limited to just classrooms. It can be gained anytime, anywhere... - Ravi Ranjan (M.Tech-NIT)

Remember that in Sass the map data type represents one or more key value pairs. In addition to the map-specific functions in the table below, you can use any of the list functions with maps as well; the map will be treated as a set of two-element lists:

nth(("red": #ff0000, "green": #00ff00), 2) //returns ("green" #00ff00)

Like lists, Sass maps are immutable. The map functions that return a map return a new map; they do not change the original arguments.

Function Description Examples
map-get($map, $key) Returns the value associated with the specified key map-get(("red": #ff0000, "green": #00ff00), "green") 

Result:
#00ff00
map-merge($map1, $map2) Returns a map containing $map2 appended to the end of $map1 map-merge(("red": #ff0000, "green": #00ff00), ("blue": #0000ff) 

Result:
("red": #ff0000, "green": #00ff00, "blue": #0000ff)
map-remove($map, $keys) Returns a map without the specified keys map-remove(("red": #ff0000, "green": #00ff00), "red") 

Result:
("green": #00ff00)
map-keys($map) Returns a list of the keys in the specified map map-keys(("red": #ff0000, "green": #00ff00)) 

Result:
("red", "green")
map-values($map) Returns a list of the values in the specified map map-values(("red": #ff0000, "green": #00ff00)) 

Result:
(#ff0000, #00ff00)
map-has-key($map, $key) Returns a Boolean value indicating whether the specified map contains the specified key map-has-key(("red": #ff0000, "green": #00ff00), blue) 

Result:
false
