The Date() constructor creates Date objects. When called as a function, it returns a string representing the current time.

The setBigUint64() method of DataView instances takes a BigInt and stores it as a 64-bit unsigned integer in the 8 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The Math.LN2 static data property represents the natural logarithm of 2, approximately 0.693:

The Math.LOG10E static data property represents the base 10 logarithm of e, approximately 0.434.

The prototype property of AsyncGeneratorFunction.prototype is shared by all async generator functions. Its value is AsyncGenerator.prototype. Each async generator function created with the async function* syntax or the AsyncGeneratorFunction() constructor also has its own prototype property, whose prototype is AsyncGeneratorFunction.prototype.prototype. When the async generator function is called, its prototype property becomes the prototype of the returned async generator object.

The AsyncGeneratorFunction() constructor creates AsyncGeneratorFunction objects.

The Promise.any() static method takes an iterable of promises as input and returns a single Promise. This returned promise fulfills when any of the input's promises fulfills, with this first fulfillment value. It rejects when all of the input's promises reject (including when an empty iterable is passed), with an AggregateError containing an array of rejection reasons.

The use() method of AsyncDisposableStack instances registers a value that implements the async disposable protocol to the stack.
