Int8Array

Syntax

new Int8Array(); // new in ES2017
new Int8Array(length);
new Int8Array(typedArray);
new Int8Array(object);
new Int8Array(buffer [, byteOffset [, length]]);

Для более детальной информации о синтаксисе конструктора смотрите TypedArray.

Properties

Int8Array.BYTES_PER_ELEMENT

Возвращает числовое значение размера элемента массива. 1 в случае с Int8Array.

Int8Array.length

Статическая длина конструктора Int8Array, всегда равна 3 (т.к. конструктор принимает до 3 аргументов). Чтобы узнать длину созданного массива, see Int8Array.prototype.length.

Int8Array.name

Возвращает строчное значение имени конструктора. В случае с Int8Array: "Int8Array".

Int8Array.prototype

Прототип для TypedArray objects.

Methods

Int8Array.from()

Creates a new Int8Array from an array-like or iterable object. See also Array.from().

Int8Array.of()

Creates a new Int8Array with a variable number of arguments. See also Array.of().

Int8Array prototype

All Int8Array objects inherit from %TypedArray%.prototype.

Properties

Int8Array.prototype.constructor

Returns the function that created an instance's prototype. This is the Int8Array constructor by default.

Int8Array.prototype.buffer Только для чтения

Returns the ArrayBuffer referenced by the Int8Array Fixed at construction time and thus read only.

Int8Array.prototype.byteLength Только для чтения

Returns the length (in bytes) of the Int8Array from the start of its ArrayBuffer. Fixed at construction time and thus read only.

Int8Array.prototype.byteOffset Только для чтения

Returns the offset (in bytes) of the Int8Array from the start of its ArrayBuffer. Fixed at construction time and thus read only.

Int8Array.prototype.length Только для чтения

Returns the number of elements hold in the Int8Array. Fixed at construction time and thus read only.

Methods

Int8Array.prototype.copyWithin()

Copies a sequence of array elements within the array. See also Array.prototype.copyWithin().

Int8Array.prototype.entries()

Returns a new Array Iterator object that contains the key/value pairs for each index in the array. See also Array.prototype.entries().

Int8Array.prototype.every()

Tests whether all elements in the array pass the test provided by a function. See also Array.prototype.every().

Int8Array.prototype.fill()

Fills all the elements of an array from a start index to an end index with a static value. See also Array.prototype.fill().

Int8Array.prototype.filter()

Creates a new array with all of the elements of this array for which the provided filtering function returns true. See also Array.prototype.filter().

Int8Array.prototype.find()

Returns the found value in the array, if an element in the array satisfies the provided testing function or undefined if not found. See also Array.prototype.find().

Int8Array.prototype.findIndex()

Returns the found index in the array, if an element in the array satisfies the provided testing function or -1 if not found. See also Array.prototype.findIndex().

Int8Array.prototype.forEach()

Calls a function for each element in the array. See also Array.prototype.forEach().

Int8Array.prototype.includes()

Determines whether a typed array includes a certain element, returning true or false as appropriate. See also Array.prototype.includes().

Int8Array.prototype.indexOf()

Returns the first (least) index of an element within the array equal to the specified value, or -1 if none is found. See also Array.prototype.indexOf().

Int8Array.prototype.join()

Joins all elements of an array into a string. See also
