    Types, methods and values for interoperability with JavaScript libraries.

    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:

    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.

    Tests whether the specified object o has a property p on itself or in its prototype chain.

    This method is the equivalent of p in o in JavaScript.

  14. def properties(o: Any): Array[String]

    Returns the names of all the enumerable properties of the specified object o, including properties in its prototype chain.

    Returns the names of all the enumerable properties of the specified object o, including properties in its prototype chain.

    This method returns the same set of names that would be enumerated by a for-in loop in JavaScript, in the same order.

    This method assumes that all keys enumerated by a for-in loop are strings. If this is not the case, calling this method is an undefined behavior of kind ClassCastException. Note that for all *ordinary* objects, the ECMAScript 2015 guarantees that this is the case. It might be false if o is a proxy object or another exotic object.

    For ordinary objects, if the underlying implementation guarantees an order for for-in loops, then this is guaranteed to be consistent with js.Object.keys, in the sense that the list returned by js.Object.keys is a sublist of the list returned by this method (not just a subset).

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
