Properties
ReadonlyasyncIterator
A method that returns the default async iterator for an object. Called by the semantics of the for-await-of statement.
ReadonlyhasInstance
A method that determines if a constructor object recognizes an object as one of the constructor’s instances. Called by the semantics of the instanceof operator.
ReadonlyisConcatSpreadable
A Boolean value that if true indicates that an object should flatten to its array elements by Array.prototype.concat.
Readonlyiterator
A method that returns the default iterator for an object. Called by the semantics of the for-of statement.
Readonlymatch
A regular expression method that matches the regular expression against a string. Called by the String.prototype.match method.
ReadonlymatchAll
A regular expression method that matches the regular expression against a string. Called by the String.prototype.matchAll method.
Readonlyprototype
A reference to the prototype.
Readonlyreplace
A regular expression method that replaces matched substrings of a string. Called by the String.prototype.replace method.
Readonlysearch
A regular expression method that returns the index within a string that matches the regular expression. Called by the String.prototype.search method.
Readonlyspecies
A function valued property that is the constructor function that is used to create derived objects.
Readonlysplit
A regular expression method that splits a string at the indices that match the regular expression. Called by the String.prototype.split method.
ReadonlytoPrimitive
A method that converts an object to a corresponding primitive value. Called by the ToPrimitive abstract operation.
ReadonlytoStringTag
A String value that is used in the creation of the default string description of an object. Called by the built-in method Object.prototype.toString.
Readonlyunscopables
An Object whose truthy properties are properties that are excluded from the 'with' environment bindings of the associated objects.
Returns a new unique Symbol value.
