  Js.Fn.arity2((key => 'v => bool)) =>

let findFirstBy: t('v) => (key => 'v => bool) => option((key, 'v));

findFirstBy m p uses funcion f to find the first key value pair to match predicate p.

let s0 = fromArray ~id:(module IntCmp) [|4,"4";1,"1";2,"2,"3""|];;
findFirstBy s0 (fun k v -> k = 4 ) = option (4, "4");;

let forEachU: t('v) => Js.Fn.arity2((key => 'v => unit)) => unit;

let forEach: t('v) => (key => 'v => unit) => unit;

forEach m f applies f to all bindings in map m. f receives the key as first argument, and the associated value as second argument. The bindings are passed to f in increasing order with respect to the ordering over the type of the keys.

let reduceU: t('v) => 'v2 => Js.Fn.arity3(('v2 => key => 'v => 'v2)) => 'v2;

let reduce: t('v) => 'v2 => ('v2 => key => 'v => 'v2) => 'v2;

reduce m a f computes (f kN dN ... (f k1 d1 a)...), where k1 ... kN are the keys of all bindings in m (in increasing order), and d1 ... dN are the associated data.

let everyU: t('v) => Js.Fn.arity2((key => 'v => bool)) => bool;

let every: t('v) => (key => 'v => bool) => bool;

every m p checks if all the bindings of the map satisfy the predicate p. Order unspecified

let someU: t('v) => Js.Fn.arity2((key => 'v => bool)) => bool;

let some: t('v) => (key => 'v => bool) => bool;

some m p checks if at least one binding of the map satisfy the predicate p. Order unspecified

let size: t('v) => int;

let toList: t('v) => list((key, 'v));

In increasing order.

let toArray: t('v) => array((key, 'v));

let fromArray: array((key, 'v)) => t('v);

let keysToArray: t('v) => array(key);

let valuesToArray: t('v) => array('v);

let minKey: t(_) => option(key);

let minKeyUndefined: t(_) => Js.undefined(key);

let maxKey: t(_) => option(key);

let maxKeyUndefined: t(_) => Js.undefined(key);

let minimum: t('v) => option((key, 'v));

let minUndefined: t('v) => Js.undefined((key, 'v));

let maximum: t('v) => option((key, 'v));

let maxUndefined: t('v) => Js.undefined((key, 'v));

let get: t('v) => key => option('v);

let getUndefined: t('v) => key => Js.undefined('v);

let getWithDefault: t('v) => key => 'v => 'v;

let getExn: t('v) => key => 'v;

let checkInvariantInternal: t(_) => unit;

raise when invariant is not held

let remove: t('v) => key => t('v);

remove m x returns a map containing the same bindings as m, except for x which is unbound in the returned map.

let removeMany: t('v) => array(key) => t('v);

let set: t('v) => key => 'v => t('v);

set m x y returns a map containing the same bindings as m, plus a binding of x to y. If x was already bound in m, its previous binding disappears.

let updateU: t('v) => key => Js.Fn.arity1((option('v) => option('v))) => t('v);

let update: t('v) => key => (option('v) => option('v)) => t('v);

let mergeU: 
  t('v) =>
  t('v2) =>
  Js.Fn.arity3((key => option('v) => option('v2) => option('c))) =>
  t('c);

let merge: 
  t('v) =>
  t('v2) =>
  (key => option('v) => option('v2) => option('c)) =>
  t('c);

merge m1 m2 f computes a map whose keys is a subset of keys of m1 and of m2. The presence of each such binding, and the corresponding value, is determined with the function f.

let mergeMany: t('v) => array((key, 'v)) => t('v);

let keepU: t('v) => Js.Fn.arity2((key => 'v => bool)) => t('v);

let keep: t('v) => (key => 'v => bool) => t('v);

keep m p returns the map with all the bindings in m that satisfy predicate p.

let partitionU: t('v) => Js.Fn.arity2((key => 'v => bool)) => (t('v), t('v));

let partition: t('v) => (key => 'v => bool) => (t('v), t('v));

partition m p returns a pair of maps (m1, m2), where m1 contains all the bindings of s that satisfy the predicate p, and m2 is the map with all the bindings of s that do not satisfy p.

let split: key => t('v) => (t('v), option('v), t('v));

split x m returns a triple (l, data, r), where l is the map with all the bindings of m whose key is strictly less than x; r is the map with all the bindings of m whose key is strictly greater than x; data is None if m contains no binding for x, or Some v if m binds v to x.

let mapU: t('v) => Js.Fn.arity1(('v => 'v2)) => t('v2);

let map: t('v) => ('v => 'v2) => t('v2);

map m f returns a map with same domain as m, where the associated value a of all bindings of m has been replaced by the result of the application of f to a. The bindings are passed to f in increasing order with respect to the ordering over the type of the keys.

let mapWithKeyU: t('v) => Js.Fn.arity2((key => 'v => 'v2)) => t('v2);

let mapWithKey: t('v) => (key => 'v => 'v2) => t('v2);
