package js

Types, methods and values for interoperability with JavaScript libraries.

This package is only relevant to the Scala.js compiler, and should not be referenced by any project compiled to the JVM.

Guide

General documentation on Scala.js is available at http://www.scala-js.org/doc/.

Overview

The trait js.Any is the root of the hierarchy of JavaScript types. This package defines important subtypes of js.Any that are defined in the standard library of ECMAScript 5.1 (or ES 6, with a label in the documentation), such as js.Object, js.Array and js.RegExp.

Implicit conversions to and from standard Scala types to their equivalent in JavaScript are provided. For example, from Scala functions to JavaScript functions and back.

The most important subtypes of js.Any declared in this package are:

js.Object, the superclass of most (all) JavaScript classes
js.Array
js.Function (and subtraits with specific number of parameters)
js.ThisFunction and its subtraits for functions that take the JavaScript this as an explicit parameter
js.Dictionary, a Map-like view of the properties of a JS object

The trait js.Dynamic is a special subtrait of js.Any. It can represent any JavaScript value in a dynamically-typed way. It is possible to call any method and read and write any field of a value of type js.Dynamic.

There are no explicit definitions for JavaScript primitive types, as one could expect, because the corresponding Scala types stand in their stead:

Boolean is the type of primitive JavaScript booleans
Double is the type of primitive JavaScript numbers
String is the type of primitive JavaScript strings (or null)
Unit is the type of the JavaScript undefined value
Null is the type of the JavaScript null value

js.UndefOr gives a scala.Option-like interface where the JavaScript value undefined takes the role of None.

A | B is an unboxed pseudo-union type, suitable to type values that admit several unrelated types in facade types.

package timers

Non-Standard Non-standard, but in general well supported methods to schedule asynchronous exeuction.

The methods in this package work in all JavaScript virtual machines supported by Scala.js (currently Rhino, Node.js and PhantomJS).

package typedarray

ECMAScript 6 The typdearray package provides facade types for JavaScript ArrayBuffer, TypeArrays and DataView.

ECMAScript 6 The typdearray package provides facade types for JavaScript ArrayBuffer, TypeArrays and DataView. Further, it provides conversions between primitive Scala arrays and TypedArrays
