length: 9;toString
toString: () => string;Returns a string representation of an array.
toLocaleString
toLocaleString: { (): string; (locales: string | string[], options?: (NumberFormatOptions & DateTimeFormatOptions) | undefined): string; };Returns a string representation of an array. The elements are converted to string using their toLocaleString methods.
pop
pop: () => number | undefined;Removes the last element from an array and returns it. If the array is empty, undefined is returned and the array is not modified.
push
push: (...items: number[]) => number;Appends new elements to the end of an array, and returns the new length of the array.
concat
concat: { (...items: ConcatArray<number>[]): number[]; (...items: (number | ConcatArray<number>)[]): number[]; };Combines two or more arrays. This method returns a new array without modifying any existing arrays.
join
join: (separator?: string | undefined) => string;Adds all the elements of an array into a string, separated by the specified separator string.
reverse
reverse: () => number[];Reverses the elements in an array in place. This method mutates the array and returns a reference to the same array.
shift
shift: () => number | undefined;Removes the first element from an array and returns it. If the array is empty, undefined is returned and the array is not modified.
slice
slice: (start?: number | undefined, end?: number | undefined) => number[];Returns a copy of a section of an array. For both start and end, a negative index can be used to indicate an offset from the end of the array. For example, -2 refers to the second to last element of the array.
sort
sort:
| (compareFn?: ((a: number, b: number) => number)
| undefined) => TransformationMatrix;Sorts an array in place. This method mutates the array and returns a reference to the same array.
splice
splice: { (start: number, deleteCount?: number | undefined): number[]; (start: number, deleteCount: number, ...items: number[]): number[]; };Removes elements from an array and, if necessary, inserts new elements in their place, returning the deleted elements.
unshift
unshift: (...items: number[]) => number;Inserts new elements at the start of an array, and returns the new length of the array.
indexOf
indexOf: (searchElement: number, fromIndex?: number | undefined) => number;Returns the index of the first occurrence of a value in an array, or -1 if it is not present.
lastIndexOf
lastIndexOf: (searchElement: number, fromIndex?: number | undefined) => number;Returns the index of the last occurrence of a specified value in an array, or -1 if it is not present.
every
every: { <S extends number>(predicate: (value: number, index: number, array: number[]) => value is S, thisArg?: any): this is S[]; (predicate: (value: number, index: number, array: number[]) => unknown, thisArg?: any): boolean; };Determines whether all the members of an array satisfy the specified test.
some
some: (predicate: (value: number, index: number, array: number[]) => unknown, thisArg?: any) => boolean;Determines whether the specified callback function returns true for any element of an array.
forEach
forEach: (callbackfn: (value: number, index: number, array: number[]) => void, thisArg?: any) => void;Performs the specified action for each element in an array.
map
map: <U>(callbackfn: (value: number, index: number, array: number[]) => U, thisArg?: any) => U[];Calls a defined callback function on each element of an array, and returns an array that contains the results.
filter
filter: { <S extends number>(predicate: (value: number, index: number, array: number[]) => value is S, thisArg?: any): S[]; (predicate: (value: number, index: number, array: number[]) => unknown, thisArg?: any): number[]; };Returns the elements of an array that meet the condition specified in a callback function.
reduce
reduce: { (callbackfn: (previousValue: number, currentValue: number, currentIndex: number, array: number[]) => number): number; (callbackfn: (previousValue: number, currentValue: number, currentIndex: number, array: number[]) => number, initialValue: number): number; <U>(callbackfn: (previousValue: U, currentValue: number, currentIndex: number, array: number[]) => U, initialValue: U): U; };Calls the specified callback function for all the elements in an array. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function.
reduceRight
reduceRight: { (callbackfn: (previousValue: number, currentValue: number, currentIndex: number, array: number[]) => number): number; (callbackfn: (previousValue: number, currentValue: number, currentIndex: number, array: number[]) => number, initialValue: number): number; <U>(callbackfn: (previousValue: U, currentValue: number, currentIndex: number, array: number[]) => U, initialValue: U): U; };Calls the specified callback function for all the elements in an array, in descending order. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function.
find
find: { <S extends number>(predicate: (value: number, index: number, obj: number[]) => value is S, thisArg?: any): S | undefined; (predicate: (value: number, index: number, obj: number[]) => unknown, thisArg?: any): number | undefined; };Returns the value of the first element in the array where predicate is true, and undefined otherwise.
findIndex
findIndex: (predicate: (value: number, index: number, obj: number[]) => unknown, thisArg?: any) => number;Returns the index of the first element in the array where predicate is true, and -1 otherwise.
fill
fill: (value: number, start?: number | undefined, end?: number | undefined) => TransformationMatrix;Changes all array elements from start to end index to a static value and returns the modified array
copyWithin
copyWithin: (target: number, start: number, end?: number | undefined) => TransformationMatrix;Returns the this object after copying a section of the array identified by start and end to the same array starting at position target
entries
entries: () => ArrayIterator<[number, number]>;Returns an iterable of key, value pairs for every entry in the array
keys
keys: () => ArrayIterator<number>;Returns an iterable of keys in the array
values
values: () => ArrayIterator<number>;Returns an iterable of values in the array
includes
includes: (searchElement: number, fromIndex?: number | undefined) => boolean;Determines whether an array includes a certain element, returning true or false as appropriate.
flatMap
flatMap: <U, This = undefined>(callback: (this: This, value: number, index: number, array: number[]) => U | readonly U[], thisArg?: This | undefined) => U[];Calls a defined callback function on each element of an array. Then, flattens the result into a new array. This is identical to a map followed by flat with depth 1.
flat
flat: <A, D extends number = 1>(this: A, depth?: D | undefined) => FlatArray<A, D>[];Returns a new array with all sub-array elements concatenated into it recursively up to the specified depth.

__@unscopables@478
__@unscopables@478: {
[K in keyof any[]]?: boolean;
