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

The buffer accessor property of DataView instances returns the ArrayBuffer or SharedArrayBuffer referenced by this view at construction time.

The delete() method of WeakSet instances removes the specified element from this WeakSet.

The has() method of WeakSet instances returns a boolean indicating whether an object exists in this WeakSet or not.

The Symbol.hasInstance static data property represents the well-known symbol @@hasInstance. The instanceof operator looks up this symbol on its right-hand operand for the method used to determine if the constructor object recognizes an object as its instance.

The endsWith() method of String values determines whether a string ends with the characters of this string, returning true or false as appropriate.

The constructor data property of an Object instance returns a reference to the constructor function that created the instance object. Note that the value of this property is a reference to the function itself, not a string containing the function's name.

The length data property of an Array instance represents the number of elements in that array. The value is an unsigned, 32-bit integer that is always numerically greater than the highest index in the array.

The [@@hasInstance]() method of Function instances specifies the default procedure for determining if a constructor function recognizes an object as one of the constructor's instances. It is called by the instanceof operator.

The lastIndexOf() method of Array instances returns the last index at which a given element can be found in the array, or -1 if it is not present. The array is searched backwards, starting at fromIndex.
