##Index

Functions

• curry(f, [arity])
• compose(...functions)
• flip(f)
• not(f)
• get(p, o)
• translate(dictionary, key)
• is(type, o)
• is_instance_of(constructor, o)
• is_equal(x, y)

##curry(f, [arity]) Curry function f. Resulting function takes single argument and returns function until receiving all arguments at which time it invokes f with all supplied arguments.

Params

• f function
• [arity=f.length] Number - Optional arity of f. Useful for currying variadic functions (accepting varying number of arguments).

Returns: function
##compose(...functions) Compose functions. Resulting function when invoked will execute functions starting with the last one and use it's result as arguments for the next one.

Params

• ...functions function

Returns: function
##flip(f) Create a function which when invoked, will call function f with arguments in reverse order.

Params

• f function

Returns: function
##not(f) Create a negation of function f. I.e. not(f)(x) = !f(x).

Params

• f function

Returns: function
##get(p, o) Gets value of property p of object o.

Params

• p String
• o Object

Returns: *
##translate(dictionary, key) Gets value of property key of object dictionary. Similar to get except with arguments reversed.

Params

• dictionary Object
• key String

Returns: *
##is(type, o) Returns true if o is of type type and false otherwise.

Params

• type String
• o Object

Returns: Boolean
##is_instance_of(constructor, o) Returns true if o has constructor.prototype somewhere in it's prototype chain and false otherwise.

Params

• constructor function
• o Object

Returns: Boolean
##is_equal(x, y) Returns true is x is strictly equal to y and false otherwise.

Params

• x *
• y *

Returns: Boolean
