The forEach() method of Set instances executes a provided function once for each value in this set, in insertion order.

The intersection() method of Set instances takes a set and returns a new set containing elements in both this set and the given set.

The isSubsetOf() method of Set instances takes a set and returns a boolean indicating if all elements of this set are in the given set.

The TypedArray.from() static method creates a new typed array from an array-like or iterable object. This method is nearly the same as Array.from().

The reduce() method of TypedArray instances executes a user-supplied "reducer" callback function on each element of the typed array, in order, passing in the return value from the calculation on the preceding element. The final result of running the reducer across all elements of the typed array is a single value. This method has the same algorithm as Array.prototype.reduce().

The text-decoration attribute defines whether text is decorated with an underline, overline and/or strike-through. It is a shorthand for the text-decoration-line and text-decoration-style properties.

The apply() method of Function instances calls this function with a given this value, and arguments provided as an array (or an array-like object).

The optional displayName property of a Function instance specifies the display name of the function.

The __proto__ accessor property of Object instances exposes the [[Prototype]] (either an object or null) of this object.

The toLocaleString() method of Object instances returns a string representing this object. This method is meant to be overridden by derived objects for locale-specific purposes.
