The every() method of Iterator instances is similar to Array.prototype.every(): it tests whether all elements produced by the iterator pass the test implemented by the provided function. It returns a boolean value.

The take() method of Iterator instances returns a new iterator helper object that yields the given number of elements in this iterator and then terminates.

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 [Symbol.iterator]() method of String values implements the iterable protocol and allows strings to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns a string iterator object that yields the Unicode code points of the string value as individual strings.

The Object.fromEntries() static method transforms a list of key-value pairs into an object.

The localeCompare() method of String values returns a number indicating whether this string comes before, or after, or is the same as the given string in sort order. In implementations with Intl.Collator API support, this method delegates to Intl.Collator.

The fontcolor() method of String values creates a string that embeds this string in a <font> element (<font color="...">str</font>), which causes this string to be displayed in the specified font color.

The finally() method of Promise instances schedules a function to be called when the promise is settled (either fulfilled or rejected). It immediately returns another Promise object, allowing you to chain calls to other promise methods.

The Object.seal() static method seals an object. Sealing an object prevents extensions and makes existing properties non-configurable. A sealed object has a fixed set of properties: new properties cannot be added, existing properties cannot be removed, their enumerability and configurability cannot be changed, and its prototype cannot be re-assigned. Values of existing properties can still be changed as long as they are writable. seal() returns the same object that was passed in.
