This library provides bindings and necessary support for JS FFI. It contains all bindings into Js namespace.

val toOption : 'a Js__.Js_internal.nullable -> 'a option

val undefinedToOption : 'a Js__.Js_internal.undefined -> 'a option

val nullToOption : 'a Js__.Js_internal.null -> 'a option

val isNullable : 'a Js__.Js_internal.nullable -> bool

val testAny : 'a -> bool

The same as test except that it is more permissive on the types of input

val null : 'a Js__.Js_internal.null

The same as empty in Js.Null will be compiled as null

val undefined : 'a Js__.Js_internal.undefined

The same as empty Js.Undefined will be compiled as undefined

val typeof : 'a -> string

typeof x will be compiled as typeof x in JS Please consider functions in Types for a type safe way of reflection

val log : 'a -> unit

A convenience function to log everything

val log2 : 'a -> 'b -> unit

val log3 : 'a -> 'b -> 'c -> unit

val log4 : 'a -> 'b -> 'c -> 'd -> unit

val logMany : 'a array -> unit

A convenience function to log more than 4 arguments

val eqNull : 'a -> 'a Js__.Js_internal.null -> bool

val eqUndefined : 'a -> 'a Js__.Js_internal.undefined -> bool

val eqNullable : 'a -> 'a Js__.Js_internal.nullable -> bool

operators

val unsafe_lt : 'a -> 'a -> bool

unsafe_lt a b will be compiled as a < b. It is marked as unsafe, since it is impossible to give a proper semantics for comparision which applies to any type

val unsafe_le : 'a -> 'a -> bool

unsafe_le a b will be compiled as a <= b. See also unsafe_lt

val unsafe_gt : 'a -> 'a -> bool

unsafe_gt a b will be compiled as a > b. See also unsafe_lt

val unsafe_ge : 'a -> 'a -> bool

unsafe_ge a b will be compiled as a >= b. See also unsafe_lt

Types for JS objects

type 'a t

This used to be mark a Js object type.

type +'a null = 'a Js__.Js_null.t

nullable, value of this type can be either null or 'a this type is the same as type t in Null

type +'a undefined = 'a Js__.Js_undefined.t

value of this type can be either undefined or 'a this type is the same as type t in Undefined

type +'a nullable = 'a Js__.Js_null_undefined.t

value of this type can be undefined, null or 'a this type is the same as type t n Null_undefined

type +'a null_undefined = 'a nullable
