Quantifiers indicate numbers of characters or expressions to match.

Character classes distinguish kinds of characters such as, for example, distinguishing between letters and digits.

The hasOwnProperty() method of Object instances returns a boolean indicating whether this object has the specified property as its own property (as opposed to inheriting it).

The findLastIndex() method of Array instances iterates the array in reverse order and returns the index of the first element that satisfies the provided testing function. If no elements satisfy the testing function, -1 is returned.

The Promise.all() static method takes an iterable of promises as input and returns a single Promise. This returned promise fulfills when all of the input's promises fulfill (including when an empty iterable is passed), with an array of the fulfillment values. It rejects when any of the input's promises rejects, with this first rejection reason.

The Object.entries() static method returns an array of a given object's own enumerable string-keyed property key-value pairs.

The JSON.stringify() static method converts a JavaScript value to a JSON string, optionally replacing values if a replacer function is specified or optionally including only the specified properties if a replacer array is specified.

The fill() method of Array instances changes all elements within a range of indices in an array to a static value. It returns the modified array.

import.meta.resolve() is a built-in function defined on the import.meta object of a JavaScript module that resolves a module specifier to a URL using the current module's URL as base.
