 ## Constant
 
-A variable that cannot be reassigned once defined.
+Bir kere tanımlandıktan sonra yeniden atanamayan değişkenlerdir.
 
 ```js
 const five = 5

-Constants are [referentially transparent](#referential-transparency). That is, they can be replaced with the values that they represent without affecting the result.

-With the above two constants the following expression will always return `true`.

 ## Functor
 
-An object that implements a `map` function which, while running over each value in the object to produce a new object, adheres to two rules:
