![]() Returns a string representing the calling array and its elements. Returns a localized string representing the calling array and its elements. ()Īdds and/or removes elements from an array. Sorts the elements of an array in place and returns the array. Returns true if at least one element in the calling array satisfies the provided testing function. ()Įxtracts a section of the calling array and returns a new array. Removes the first element from an array and returns that element. (First becomes the last, last becomes first.) () Reverses the order of the elements of an array in place. ()Įxecutes a user-supplied "reducer" callback function on each element of the array (from right to left), to reduce it to a single value. ()Įxecutes a user-supplied "reducer" callback function on each element of the array (from left to right), to reduce it to a single value. ()Īdds one or more elements to the end of an array, and returns the new length of the array. Removes the last element from an array and returns that element. Returns a new array containing the results of invoking a function on every element in the calling array. Returns the last (greatest) index at which a given element can be found in the calling array, or -1 if none is found. Returns a new array iterator that contains the keys for each index in the calling array. Joins all elements of an array into a string. Returns the first (least) index at which a given element can be found in the calling array. ()ĭetermines whether the calling array contains a value, returning true or false as appropriate. Groups the elements of an array into a Map according to values returned by a test function. Groups the elements of an array into an object according to the strings returned by a test function. ()Ĭalls a function for each element in the calling array. Returns a new array formed by applying a given callback function to each element of the calling array, and then flattening the result by one level. Returns a new array with all sub-array elements concatenated into it recursively up to the specified depth. Returns the index of the last element in the array that satisfies the provided testing function, or -1 if no appropriate element was found. Returns the value of the last element in the array that satisfies the provided testing function, or undefined if no appropriate element is found. Returns the index of the first element in the array that satisfies the provided testing function, or -1 if no appropriate element was found. Returns the value of the first element in the array that satisfies the provided testing function, or undefined if no appropriate element is found. Returns a new array containing all elements of the calling array for which the provided filtering function returns true. ()įills all the elements of an array from a start index to an end index with a static value. Returns true if every element in the calling array satisfies the testing function. Returns a new array iterator object that contains the key/value pairs for each index in an array. ()Ĭopies a sequence of array elements within an array. Returns a new array that is the calling array joined with other array(s) and/or value(s). Accepts negative integers, which count back from the last item. Returns the array item at the given index.
