The Number.isSafeInteger() static method determines whether the provided value is a number that is a safe integer.

The Math.ceil() static method always rounds up and returns the smallest integer greater than or equal to a given number.

The Math.atan2() static method returns the angle in the plane (in radians) between the positive x-axis and the ray from (0, 0) to the point (x, y), for Math.atan2(y, x).

The Symbol.unscopables static data property represents the well-known symbol @@unscopables. The with statement looks up this symbol on the scope object for a property containing a collection of properties that should not become bindings within the with environment.

The Symbol.species static data property represents the well-known symbol @@species. Methods that create copies of an object may look up this symbol on the object for the constructor function to use when creating the copy.

The Symbol.asyncIterator static data property represents the well-known symbol @@asyncIterator. The async iterable protocol looks up this symbol for the method that returns the async iterator for an object. In order for an object to be async iterable, it must have an @@asyncIterator key.

The Symbol.isConcatSpreadable static data property represents the well-known symbol @@isConcatSpreadable. The Array.prototype.concat() method looks up this symbol on each object being concatenated to determine if it should be treated as an array-like object and flattened to its array elements.

The Atomics.and() static method computes a bitwise AND with a given value at a given position in the array, and returns the old value at that position. This atomic operation guarantees that no other write happens until the modified value is written back.

The Atomics.notify() static method notifies up some agents that are sleeping in the wait queue.

The detached accessor property of ArrayBuffer instances returns a boolean indicating whether or not this buffer has been detached (transferred).
