java.lang.Object
- jsinterop.base.Js

```
public final class Js
extends java.lang.Object
```
Utilities to provide access to JavaScript language constructs that are not available in pure Java.
Note that this class avoids providing replacements for stuff that is already available via a pure Java or Elemental and enforce safe (runtime-checked) coding practices.

Method Detail

undefined

@JsProperty(namespace="<window>",
            name="undefined")
public static java.lang.Object undefined()

arguments

@JsProperty(namespace="<window>",
            name="arguments")
public static JsArrayLike<java.lang.Object> arguments()

debugger

@JsProperty(namespace="<window>",
            name="debugger")
public static void debugger()

typeof

@JsMethod(namespace="<window>")
public static java.lang.String typeof(java.lang.Object obj)

global

public static JsPropertyMap<java.lang.Object> global()

asConstructorFn

public static <T> JsConstructorFn<T> asConstructorFn(java.lang.Class<T> clazz)

asAny

public static Any asAny(java.lang.Object obj)

asPropertyMap

public static JsPropertyMap<java.lang.Object> asPropertyMap(java.lang.Object obj)

Returns JsPropertyMap view of provided object.

asArrayLike

public static JsArrayLike<java.lang.Object> asArrayLike(java.lang.Object obj)

Returns JsArrayLike view of provided array-like object.

asArray

public static Any[] asArray(java.lang.Object obj)

asString

public static java.lang.String asString(java.lang.Object obj)

asBoolean

public static boolean asBoolean(java.lang.Object obj)

asDouble

public static double asDouble(java.lang.Object obj)

asFloat

public static float asFloat(java.lang.Object obj)

asLong

public static long asLong(java.lang.Object obj)

asInt

public static int asInt(java.lang.Object obj)

asShort

public static short asShort(java.lang.Object obj)

asChar

public static char asChar(java.lang.Object obj)

asByte

public static byte asByte(java.lang.Object obj)

cast
```
public static <T> T cast(java.lang.Object obj)
```
Performs checked cast to lefthand-side type.
This is useful for cases when Java won't allow you otherwise, like casting from a native interface to a final Java class (like String).

uncheckedCast
```
public static <T> T uncheckedCast(java.lang.Object obj)
```
Performs unchecked cast to lefthand-side type.
This method exists in order to lie to the type system, it is not an optimization. You should *ALWAYS* prefer regular casting over this which also optimizes for production. Using this method can leak incorrect types to the rest of the system which will result in hard to debug problems.

andAlso

public static <T> T andAlso(T obj1,
                            T obj2)

Applies JavaScript logical "and" operator (&&) on given objects.

orElse

public static <T> T orElse(T obj1,
                           T obj2)

Applies JavaScript logical "or" operator (||) on given objects.

isTruthy

public static boolean isTruthy(java.lang.Object obj)

isFalsy

public static boolean isFalsy(java.lang.Object obj)

isTripleEqual
```
public static boolean isTripleEqual(java.lang.Object o1,
                                    java.lang.Object o2)
```
Returns true if two objects are same.
This method mostly behaves similar to Java == operator except that it doesn't return true for null==undefined comparison.

coerceToDouble

public static double coerceToDouble(java.lang.Object d)

Coerces any object to number using + operation.

coerceToInt
```
public static int coerceToInt(java.lang.Object d)
```
Coerces any object to 32 bit signed number using |0 operation.
