# StaticArray

A randomly accessible sequence of values of a generic type with a fixed length.

The StaticArray API is similar to the Array API, with the important difference that it has a fixed length that cannot change. Unlike a normal Array, a StaticArray does not have a separate backing buffer, so no level of indirection, and as such can have minimal overhead and performance characteristics very similar to arrays in C.

# Constructor

```
new StaticArray<T>(length: i32)
```
Constructs a new static array.

# Static members

function fromArray<T>(source: Array<T>): StaticArray<T>

Creates a static array from a normal array.

function concat<T>(source: StaticArray<T>, other: StaticArray<T>): StaticArray<T>

Like the instance member concat, but taking and returning a StaticArray.

function slice<T>(source: StaticArray<T>, start?: i32, end?: i32): StaticArray<T>

Like the instance member slice, but returning a StaticArray.

# Instance members

# Fields

```
readonly length: i32
```
The fixed length of this static array.

# Methods

```
function at(pos: i32): T
```
Gets the element at the specified position. This method allows for positive and negative integers. Negative integers count back from the last element.
```
function concat(other: Array<T>): Array<T>
```
Concatenates the values of this static and the other normal array to a new normal array, in this order.
```
function copyWithin(target: i32, start: i32, end?: i32): this
```
Copies a region of an array's values over the respective values starting at the target location.
```
function every(fn: (value: T, index: i32, self: StaticArray<T>) => bool): bool
```
Calls the specified function with every value of the array until it finds the first value for which the function returns false. Returns true if all functions returned true or the array is empty, otherwise false.
```
function fill(value: T, start?: i32, end?: i32): this
```
Replaces the values of the array from start inclusive to end exclusive in place with the specified value, returning the array.
```
function filter(fn: (value: T, index: i32, self: StaticArray<T>) => bool): Array<T>
```
Calls the specified function with every value of the array, returning a new array with all values for which the function returned true.
```
function findIndex(fn: (value: T, index: i32, self: StaticArray<T>) => bool): i32
```
Calls the specified function with every value of the array until it finds the first value for which the function returns true, returning its index. Returns -1 if that's never the case.
```
function findLastIndex(fn: (value: T, index: i32, self: StaticArray<T>) => bool): i32;
```
Calls the specified function with every value of the array starting at the end until it finds the first value for which the function returns true, returning its index. Returns -1 if that's never the case.

function forEach(fn: (value: T, index: i32, self: StaticArray<T>) => void): void

Calls the specified function with every value of the array.

```
function includes(value: T, fromIndex?: i32): bool
```
Tests if the array includes the specified value, optionally providing a starting index.
```
function indexOf(value: T, fromIndex?: i32): i32
```
Gets the first index where the specified value can be found in the array. Returns -1 if not found.
```
function join(separator?: string): string
```
Concatenates all values of the array to a string, separated by the specified separator (default: ,).
```
function lastIndexOf(value: T, fromIndex?: i32): i32
```
Gets the last index where the specified value can be found in the array. Returns -1 if not found.
```
function map<U>(fn: (value: T, index: i32, self: StaticArray<T>) => U): Array<U>
```
Calls the specified function with every value of the array, returning a new array of the function's return values.
```
function slice(start?: i32, end?: i32): Array<T>
```
Returns a shallow copy of this static array's values from begin inclusive to end exclusive, as a new normal array. If omitted, end defaults to the end of the array.
```
function some(fn: (value: T, index: i32, self: StaticArray<T>) => bool): bool
```
Calls the specified function with every value of the array until it finds the first value for which the function returns true, returning true. Returns false otherwise or if the array is empty.
```
function sort(fn?: (a: T, b: T) => i32): this
```
Sorts the values of the array in place, using the specified comparator function, modifying the array before returning it. The comparator returning a negative value means a < b, a positive value means a > b and 0 means that both are equal. Unlike in JavaScript, where an implicit conversion to strings is performed, the comparator defaults to compare two values of type T.
```
function reduce<U>(
  fn: (accumValue: U, currentValue: T, index: i32, self: StaticArray<T>) => U,
  initialValue: U
): U
```
Calls the specified reducer function with each value of the array, resulting in a single return value. The respective previous reducer function's return value is remembered in accumValue, starting with initialValue, becoming the final return value in the process.
```
function reduceRight<U>(
  fn: (accumValue: U, currentValue: T, index: i32, self: StaticArray<T>) => U,
  initialValue: U
): U
```
Calls the specified reducer function with each value of the array, from right to left, resulting in a single return value. See Array#reduce for the reducer function's signature.
```
function reverse(): this
```
Reverses an array's values in place, modifying the array before returning it.
```
function toString(): string
```
Returns the result of join().
