The static Reflect.getPrototypeOf() method is the same method as Object.getPrototypeOf(). It returns the prototype (i.e. the value of the internal [[Prototype]] property) of the specified object.

ECMAScript6 JavaScript Method Reflect

The static Reflect.has() method works like the in operator as a function.

ECMAScript6 JavaScript Method Reflect

The static Reflect.isExtensible() method determines if an object is extensible (whether it can have new properties added to it). It is similar to Object.isExtensible(), but with some differences.

ECMAScript6 JavaScript Method Reflect

The static Reflect.ownKeys() method returns an array of the target object's own property keys.

ECMAScript6 JavaScript Method Reflect

The static Reflect.preventExtensions() method prevents new properties from ever being added to an object (i.e. prevents future extensions to the object). It is similar to Object.preventExtensions(), but with some differences.

ECMAScript6 JavaScript Method Reflect

The static Reflect.set() method works like setting a property on an object.

ECMAScript6 JavaScript Method Reflect

The static Reflect.setPrototypeOf() method is the same method as Object.setPrototypeOf(). It sets the prototype (i.e., the internal [[Prototype]] property) of a specified object to another object or to null.

ECMAScript6 JavaScript Method Reflect

The Set object lets you store unique values of any type, whether primitive values or object references.

ECMAScript6 JavaScript set

The Set[@@species] accessor property returns the Set constructor.

ECMAScript6 JavaScript Property set

The Set.prototype property represents the prototype for the Set constructor.

SIMD (pronounced "sim-dee") is short for Single Instruction/Multiple Data which is one classification of computer architectures. SIMD operations perform the same computation on multiple data points resulting in data level parallelism and thus performance gains, for example for 3D graphics and video processing, physics simulations or cryptography, and other domains.

Experimental JavaScript SIMD

The static SIMD.%type%.abs() method returns a new SIMD data type with absolute values. This operation exists only on floating point SIMD types.

Experimental JavaScript Method SIMD

The static SIMD.%type%.add() method returns a new instance with the lane values added (a + b).

Experimental JavaScript Method SIMD

The static SIMD.%type%.addSaturate() method returns a new instance with the lane values added (a + b) and saturating behavior on overflow.

Experimental JavaScript Method SIMD

The static SIMD.%BooleanType%.allTrue() method returns a Boolean indicating whether or not all lanes hold a true value.

Experimental JavaScript Method SIMD

The static SIMD.%type%.and() method returns a new instance with the logical AND of the lane values (a & b). This operation exists only on integer and boolean SIMD types.

Experimental JavaScript Method SIMD

The static SIMD.%BooleanType%.anyTrue() method returns a Boolean indicating whether or not any of the lanes hold a true value.

Experimental JavaScript SIMD

The static SIMD.%type%.check() method returns a SIMD data type if the parameter is a valid SIMD data type and the same as %type%. Otherwise, a TypeError is thrown.

Experimental JavaScript Method SIMD

The static SIMD.%type%.div() method returns a new instance with the lane values divided (a / b). This function is defined only on floating point SIMD types.

Experimental JavaScript Method SIMD

The static SIMD.%type%.equal() method returns a selection mask with values depending on a strict equality comparison (a === b) in each lane.
