The Math.sqrt() static method returns the square root of a number. That is

The Math.log10() static method returns the base 10 logarithm of a number. That is

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

The next() method of Generator instances returns an object with two properties done and value. You can also provide a parameter to the next method to send a value to the generator.

The Date.now() static method returns the number of milliseconds elapsed since the epoch, which is defined as the midnight at the beginning of January 1, 1970, UTC.

The SharedArrayBuffer() constructor creates SharedArrayBuffer objects.

The fill() method of TypedArray instances changes all elements within a range of indices in a typed array to a static value. It returns the modified typed array. This method has the same algorithm as Array.prototype.fill().

The [@@iterator]() method of TypedArray instances implements the iterable protocol and allows typed arrays to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns an array iterator object that yields the value of each index in the typed array.

The entries() method of TypedArray instances returns a new array iterator object that contains the key/value pairs for each index in the typed array. This method has the same algorithm as Array.prototype.entries().

The reverse() method of TypedArray instances reverses a typed array in place and returns the reference to the same typed array, the first typed array element now becoming the last, and the last typed array element becoming the first. In other words, elements order in the typed array will be turned towards the direction opposite to that previously stated. This method has the same algorithm as Array.prototype.reverse().
