hasOwn

Failsafe function that uses Object.prototype.hasOwnProperty() and return false in case if target is not a valid object.

Note: It uses arrow functions that may not be supported by some old environments.

You better use lodash/has.

isFunction

The isFunction() is a simple wrapper over

typeof value === 'function'

Previously I was using instanceof but it seems using typeof should faster. And since I do not like putting string literal here and there, I've decided to wrap it into a function.

withProxy

Factory generator for wrapping objects with Proxy. Applies construct and apply traps to function targets.

const myFactory = withProxy({
  get: myGetHandler,
  set: mySetHandler,
  apply: myApplyHandler,
  construct: myConstructHandler,
});

getClass()

Simple function wrapper over Object.getPrototypeOf().
Additionally provides functions to getClassName() and getParentClass().

Demo on jsFiddle.

deferred()

Simple function to create Promise with exposed resolve() and reject() handlers.

import deferred from '@actualwave/deferred';

const { resolve, reject, promise } = deferred();

jQuery events to DOM

Listens for jQuery events to re-dispatch them from DOM element as CustomEvent. To redispatch Bootstrap 4 modal events from modal DOM element

import translateJQueryEventsToDOM from '@actualwave/jquery-events-to-dom';

translateJQueryEventsToDOM()(
  'show.bs.modal',
 'shown.bs.modal',

Closure Value

Factory functions to create a value storage hidden in a closure

singleValueFactory() - creates storage for a single value
valuesMapFactory() - creates storage with Map hidden, allows adding key/value pairs
valuesSetFactory() - creates storage with Set hidden, allows adding unique values
