  : never
Source

Endomorphisms ​

[T] endo ​

typescript
type endo<$T = any> = ($value: $T) => $T
Source

Endomorphism

  • a function from a type to itself.

Unlike identity, this doesn't preserve the exact value, just ensures the output type matches the input type.

Examples:

typescript
// Builder pattern
type 
BuilderOp
 = 
Fn
.
endo
<
StringBuilder
>
const 
addText
: 
BuilderOp
 = 
sb
 => 
sb
.append('text')

// Transformations
type 
StringTransform
 = 
Fn
.
endo
<string>
const 
uppercase
: 
StringTransform
 = 
s
 => 
s
.toUpperCase()
const 
trim
: 
StringTransform
 = 
s
 => 
s
.trim()

// Chainable operations
type 
ChainOp
 = 
Fn
.
endo
<
ChainableAPI
>
const 
configure
: 
ChainOp
 = 
api
 => 
api
.setOption('key', 'value')

[F] endo ​

typescript
(value: any): any
Source

The identity endomorphism

  • returns the value unchanged. This is both an endomorphism and the identity function.

Examples:

typescript
const 
result
 = 
Fn
.endo(5) // returns 5
const 
obj
 = { 
a
: 1 }
const 
same
 = 
Fn
.endo(
obj
) // returns the same object reference

Introspection ​

[U] Parameter ​

typescript
type Parameter = { type: 'name'; value: string } | {
  type: 'destructured'
  names: string[]
}
Source

[F] analyzeFunction ​

typescript
(fn: (...args: any[]) => unknown): { body: string; parameters: Parameter[]; }
Source

Parameters:

  • fn - The function to analyze

Returns: An object containing the function's cleaned body and parameters

Throws:

  • Error If the function cannot be parsed or has invalid structure

Analyze a function to extract its parameter information and body.

Parses a function's string representation to extract:

  • Parameter names (both regular and destructured parameters)
  • Function body (both statement and expression forms, trimmed and dedented)

The returned body is already cleaned: leading/trailing whitespace removed and common indentation stripped away for clean display in its isolated form.

Examples:

typescript
const 
fn
 = (
a
, { 
b
, 
c
 }) => 
a
 + 
b
 + 
c

const 
info
 = 
Fn
.analyzeFunction(
fn
)
// info.parameters: [{ type: 'name', value: 'a' }, { type: 'destructured', names: ['b', 'c'] }]
// info.body: "a + b + c" (already trimmed and dedented)

[F] isUnary ​

typescript
(fn: (...args: any[]) => unknown): boolean
Source

Parameters:

  • fn - The function to check

Returns: True if the function has exactly one parameter, false otherwise

Check if a function is unary (has exactly one parameter).

Examples:

typescript
const 
unary
 = (
x
: number) => 
x
 * 2
const 
binary
 = (
a
: number, 
b
: number) => 
a
 + 
b

const 
nullary
 = () => 42


Fn
.isUnary(
unary
) // true

Fn
.isUnary(
binary
) // false

Fn
.isUnary(
nullary
) // false

Partial Application ​

[C] _ ​

typescript
typeof _
Source

Symbol used to represent a hole in partial application. When used as an argument, indicates that the parameter should be deferred.

Examples:

typescript
const 
add
 = (
a
: number, 
b
: number) => 
a
 + 
b

const 
addOne
 = partial(
add
, _, 1) // (a: number) => number

addOne
(5) // 6

[T] _ ​

typescript
type _ = typeof _
Source

[F] isHole ​

typescript
(value: unknown): boolean
Source

Type guard to check if a value is a hole.

[F] partial ​

typescript
<$Fn extends Fn.AnyAny, $Args extends readonly unknown[] > (fn: $Fn, ...args ?: $Args): any
Source

Parameters:

  • fn - The function to partially apply
  • args - Arguments with holes (_) for deferred parameters

Returns: A new function accepting the remaining arguments, or the result if all arguments are provided

Create a partially applied function by providing some arguments upfront. Use the hole symbol (_) to defer parameters.

Examples:

typescript
// Basic usage
const 
add
 = (
a
: number, 
b
: number) => 
a
 + 
b

const 
addOne
 = 
Fn
.partial(
add
, _, 1)

addOne
(5) // 6

// Multiple holes
const 
greet
 = (
greeting
: string, 
name
: string, 
punctuation
: string) =>
  `${
greeting
}, ${
name
}${
punctuation
}`
const 
casualGreet
 = 
Fn
.partial(
greet
, 'Hey', _, '!')

casualGreet
('Alice') // 'Hey, Alice!'

// All arguments provided - executes immediately
const 
result
 = 
Fn
.partial(
add
, 1, 2) // 3

[C] apply ​

typescript
;(<$Fn extends Fn.AnyAny, const $Args extends readonly unknown[]>(
  fn: $Fn,
  ...args: $Args
) => any)
Source

Type-safe partial application with automatic type inference. This is an alias for partial with a more explicit name.

Examples:

typescript
const 
multiply
 = (
a
: number, 
b
: number, 
c
: number) => 
a
 * 
b
 * 
c

const 
double
 = 
Fn
.apply(
multiply
, 2, _, 1)

double
(5) // 10

[F] defer ​

typescript
<$Fn extends Fn.AnyAny>(fn: $Fn, ...args ?: Parameters<$Fn>): () => ReturnType<$Fn>
Source

Helper to create a deferred computation using partial application. Useful for creating thunks or delayed evaluations.

Examples:

typescript
const 
expensiveComputation
 = (
a
: number, 
b
: number) => {
  
console
.
log
('Computing...')
  return 
a
 * 
b

}

const 
defer
red
 = 
Fn
.defer(
expensiveComputation
, 5, 10)
// Nothing logged yet

const 
result
 = 
deferred
() // Logs: 'Computing...'
// result: 50

[F] isPartialArg ​

typescript
(_value: unknown): boolean
Source

Check if a value is potentially a partially applicable argument (either a hole or a regular value).

Source

[T] GuardedType ​

typescript
type GuardedType<$T> = $T extends (x: any) => x is infer __u__ ? __u__ : never
Source

Extract the guarded type from a type guard function.

Examples:

typescript
const 
isString
 = (
x
: any): 
x
 is string => typeof 
x
 === 'string'
type 
T
 = 
GuardedType
<typeof 
isString
> // string

[T] ReturnExtract ​

typescript
type ReturnExtract<$Type, $Fn extends AnyAny> = $Fn extends
  (...args: infer __args__) => infer __return__ ? (
    ...args: __args__
  ) => __return__ extends Prom.AnyAny
    ? Promise<Extract<Awaited<__return__>, $Type>>
    : Extract<__return__, $Type>
  : never
Source

Modify function such that it only returns the given type.

Automatically handles async functions by unwrapping the Promise, extracting the type, and rewrapping in a Promise. For sync functions, the type is extracted directly.

Assumes that the given type is among the possible return types of the function.

Examples:

typescript
// Sync function
type 
Fn1
 = (
x
: number) => string | number
type 
Result1
 = 
ReturnExtract
<string, 
Fn1
> // (x: number) => string

// Async function - automatically unwraps and rewraps Promise
type 
Fn2
 = (
x
: number) => 
Promise
<string | number>
type 
Result2
 = 
ReturnExtract
<string, 
Fn2
> // (x: number) => Promise<string>

[T] ReturnReplace ​

typescript
type ReturnReplace<$Fn extends AnyAny, $Type> = $Fn extends
  (...args: infer __args__) => infer __return__ ? (...args: __args__) => $Type
  : never
Source

[T] ReturnExclude ​

typescript
type ReturnExclude<$Type, $Fn extends AnyAny> = $Fn extends
  (...args: infer __args__) => infer __return__ ? (
    ...args: __args__
  ) => __return__ extends Prom.AnyAny
    ? Promise<Exclude<Awaited<__return__>, $Type>>
    : Exclude<__return__, $Type>
  : never
Source

Modify function such that it does not return the given type.

Automatically handles async functions by unwrapping the Promise, excluding the type, and rewrapping in a Promise. For sync functions, the type is excluded directly.

If function does not return the given the type, then this is effectively an identity function.

Examples:

typescript
// Sync function
type 
Fn1
 = (
x
: number) => string | null
type 
Result1
 = 
ReturnExclude
<null, 
Fn1
> // (x: number) => string

// Async function - automatically unwraps and rewraps Promise
type 
Fn2
 = (
x
: number) => 
Promise
<string | null>
type 
Result2
 = 
ReturnExclude
<null, 
Fn2
> // (x: number) => Promise<string>

[T] ReturnExcludeNull ​

typescript
type ReturnExcludeNull<$Fn extends AnyAny> = ReturnExclude<null, $Fn>
Source

[T] ReturnInclude ​

typescript
type ReturnInclude<$Type, $Fn extends AnyAny> = $Fn extends
  (...args: infer __args__) => infer __return__ ? (
    ...args: __args__
  ) => __return__ extends Prom.AnyAny ? Promise<$Type | Awaited<__return__>>
    : $Type | __return__
  : never
Source

Modify function such that it can return an additional type along with its original return types.

Automatically handles async functions by unwrapping the Promise, adding the type to the union, and rewrapping in a Promise. For sync functions, the type is added directly to the return type union.

This is useful for functions that may return early with a specific type (like void).

Examples:

typescript
// Sync function
type 
Fn1
 = (
x
: number) => string
type 
Result1
 = 
ReturnInclude
<null, 
Fn1
> // (x: number) => string | null

// Async function - automatically unwraps and rewraps Promise
type 
Fn2
 = (
x
: number) => 
Promise
<string>
type 
Result2
 = 
ReturnInclude
<null, 
Fn2
> // (x: number) => Promise<string | null>
