Next, this value is rounded to nearest Number type value. Boolean If one of the operands is a Boolean, the Boolean operand is converted to 1 if it is true, or to 0 if it is false. Object If an object is compared with a number or string, JavaScript attempts to return the default value for the object.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
In mathematics and computer science, a higher-order function (HOF) is a function that does at least one of the following: takes one or more functions as arguments (i.e. a procedural parameter, which is a parameter of a procedure that is itself a procedure), returns a function or value as its result. All other functions are first-order functions.
This JavaScript example implementation provides the toJSON method used by the JSON.stringify() [9] function to serialize the class into a simple string instead of a composite data type. It calls Object.freeze() to make the instance immutable. [10] It overrides the built-in toString() method [11] and the valueOf() method. [12]

In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...
In Haskell, the polymorphic function map :: (a -> b) -> [a] -> [b] is generalized to a polytypic function fmap :: Functor f => (a -> b) -> f a -> f b, which applies to any type belonging the Functor type class. The type constructor of lists [] can be defined as an instance of the Functor type class using the map function from the previous example:
