Optional thisArg: anyA value to use as this when executing callbackfn.
true if all elements pass the callback test, false otherwise.
Sets every element of the map to the specified value. Similar to Array#fill().

Creates a new map with all elements that pass a test specified in the callback. Similar to Array#filter().
A function to test every element of the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
A map with elements that passed the provided test.
Returns the first element in the map that satisfies the provided test. Similar to Array#find().
A function to test every element of the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
The first element that satisfies the test. If no element is found, undefined is returned.
Returns the first key in the map that satisfies the provided test. Similar to Array#findIndex().
A function to test every element of the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
The first key that satisfies the test. If no element is found, undefined is returned.
Returns a new map created by applying a specified callback function to each element of the map, then flattening the result by 1 level.
Identical to ExtendedMap#map() followed by flattening by a depth of 1.
Similar to Array#flatMap().
A function to apply to every element of the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
The new map.
Executes the provided function once for each element in the map.
Derived from the Map#forEach() method, however this is returned instead of void.
The function to execute for each element in the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
The map.
Returns a specified element from the map. Derived from the Map#get() method.
The key of the element.
The element with the specified key, or undefined if no element matches the key.
Checks if the map has an element with the specified key. Derived from the Map#has() method.
The key to test.
true if an element is found, false otherwise.
Returns a new iterator object that contains keys for each element in the map. Derived from the Map#keys() method.
The new iterator object.
Creates an array filled with the results from calling a specified callback function on each element of the map. Similar to Array#map().
A function to apply to every element of the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
The array.
Executes a specified reducer callback function on each element of the map to produce a single value. Similar to Array#reduce().
A reducer function to apply to every element of the map.
Optional initialValue: TA value to initialize previousValue in the callback function with.
The result of the reducer.
Adds or modifies an element with the specified key. Derived from the Map#set() method.
The key of the element to add / modify.
The new value of the specified element.
The map.
Tests if any element in the map satisfies a test specified in the callback. Similar to Array#some().
A function to test every element of the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
true if a single element passes the callback test, false otherwise.
Removes all elements in the map that satisfy a specified test.
A function to test every element of the map.
Optional thisArg: anyA value to use as this when executing callbackfn.
A map containing the removed elements.
Returns a new iterator object that contains values for each element in the map. Derived from the Map#values() method.
The new iterator object.
