Functions

asByteArray

inline fun Int8Array<*>.asByteArray(): ByteArray

asList

fun <T : JsAny?> ArrayLike<T>.asList(): List<T>

fun at(index: Int): JsByte?

Returns the item located at the specified index.

copyWithin

fun copyWithin(target: Int, start: Int, end: Int = definedExternally): Int8Array

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

open override fun entries(): JsIterator<JsTuple2<JsInt, JsByte>>

every

fun every(predicate: (value: JsByte) -> Unit): Boolean

Determines whether all the members of an array satisfy the specified test.

fill

fun fill(value: JsByte, start: Int = definedExternally, end: Int = definedExternally): Int8Array

Changes all array elements from start to end index to a static value and returns the modified array

filter

fun filter(predicate: (value: JsByte) -> Boolean): Int8Array<ArrayBuffer>

Returns the elements of an array that meet the condition specified in a callback function.

find

fun find(predicate: (value: JsByte) -> Boolean): JsByte?

Returns the value of the first element in the array where predicate is true, and undefined otherwise.

findIndex

fun findIndex(predicate: (value: JsByte) -> Boolean): Int

Returns the index of the first element in the array where predicate is true, and -1 otherwise.

findLast

fun findLast(predicate: (value: JsByte) -> Boolean): JsByte?

Returns the value of the last element in the array where predicate is true, and undefined otherwise.

findLastIndex

fun findLastIndex(predicate: (value: JsByte) -> Boolean): Int

Returns the index of the last element in the array where predicate is true, and -1 otherwise.

forEach

open override fun forEach(action: (item: JsByte) -> Unit)

Performs the specified action for each element in an array.

get

open operator fun get(index: Int): JsByte

open operator fun get(key: Symbol.iterator): () -> JsIterator<JsByte>

includes

fun includes(searchElement: JsByte, fromIndex: Int = definedExternally): Boolean

Determines whether an array includes a certain element, returning true or false as appropriate.

indexOf

fun indexOf(searchElement: JsByte, fromIndex: Int = definedExternally): Int

Returns the index of the first occurrence of a value in an array.

iterator

open inline operator fun iterator(): Iterator<JsByte>

join

fun join(separator: String = definedExternally): String

Adds all the elements of an array separated by the specified separator string.

keys

open override fun keys(): JsIterator<JsInt>

lastIndexOf

fun lastIndexOf(searchElement: JsByte, fromIndex: Int = definedExternally): Int

Returns the index of the last occurrence of a value in an array.

map

fun map(transform: (value: JsByte) -> JsByte): Int8Array<ArrayBuffer>

Calls a defined callback function on each element of an array, and returns an array that contains the results.

reduce

fun reduce(operation: (previousValue: JsByte, currentValue: JsByte, currentIndex: Int) -> JsByte): JsByte

fun reduce(operation: (previousValue: U, currentValue: JsByte, currentIndex: Int) -> 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

fun reduceRight(operation: (previousValue: JsByte, currentValue: JsByte, currentIndex: Int) -> JsByte): JsByte

fun reduceRight(operation: (previousValue: U, currentValue: JsByte, currentIndex: Int) -> 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.
