The toSpliced() method of Array instances is the copying version of the splice() method. It returns a new array with some elements removed and/or replaced at a given index.

The Atomics.pause() static method provides a micro-wait primitive that hints to the CPU that the caller is spinning while waiting on access to a shared resource. This allows the system to reduce the resources allocated to the core (such as power) or thread, without yielding the current thread.

The Reflect.setPrototypeOf() static method is like Object.setPrototypeOf() but returns a Boolean. It sets the prototype (i.e., the internal [[Prototype]] property) of a specified object.

The Reflect.deleteProperty() static method is like the delete operator, but as a function. It deletes a property from an object.

The set() method of WeakMap instances adds a new element with a specified key and value to this WeakMap.

The WeakMap() constructor creates WeakMap objects.
