interface Uint8ClampedArray
Private

A typed array of 8-bit unsigned integer (clamped) values. The contents are initialized to 0. If the requested number of bytes could not be allocated an exception is raised.

Index Signatures

[index: number] : number

Properties

readonly
BYTES_PER_ELEMENT: number

The size in bytes of each element in the array.

The ArrayBuffer instance referenced by the array.

readonly
byteLength: number

The length in bytes of the array.

readonly
byteOffset: number

The offset in bytes of the array.

readonly
length: number

The length of the array.

Methods

copyWithin(
target: number,
start: number,
end?: number,
): this

Returns the this object after copying a section of the array identified by start and end to the same array starting at position target

every(
predicate: (
value: number,
index: number,
) => unknown,
thisArg?: any,
): boolean

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

fill(
value: number,
start?: number,
end?: number,
): this

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

filter(
predicate: (
value: number,
index: number,
) => any,
thisArg?: any,
): Uint8ClampedArray

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

find(
predicate: (
value: number,
index: number,
) => boolean,
thisArg?: any,
): number | undefined

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

findIndex(
predicate: (
value: number,
index: number,
) => boolean,
thisArg?: any,
): number

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

forEach(
callbackfn: (
value: number,
index: number,
) => void,
thisArg?: any,
): void

Performs the specified action for each element in an array.

indexOf(
searchElement: number,
fromIndex?: number,
): number

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

join(separator?: string): string

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

lastIndexOf(
searchElement: number,
fromIndex?: number,
): number

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

map(
callbackfn: (
value: number,
index: number,
) => number,
thisArg?: any,
): Uint8ClampedArray

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

reduce(callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
) => number): number

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.

reduce(
callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
) => number,
initialValue: number,
): number
reduce<U>(
callbackfn: (
previousValue: U,
currentValue: number,
currentIndex: 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(callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
) => number): number

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.

reduceRight(
callbackfn: (
previousValue: number,
currentValue: number,
currentIndex: number,
) => number,
initialValue: number,
): number
reduceRight<U>(
callbackfn: (
previousValue: U,
currentValue: number,
currentIndex: 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.

Reverses the elements in an Array.

set(
array: ArrayLike<number>,
offset?: number,
): void

Sets a value or an array of values.

slice(
start?: number,
end?: number,
): Uint8ClampedArray

Returns a section of an array.

some(
predicate: (
value: number,
index: number,
) => unknown,
thisArg?: any,
): boolean

Determines whether the specified callback function returns true for any element of an array.

sort(compareFn?: (
a: number,
b: number,
) => number): this

Sorts an array.

subarray(
begin?: number,
end?: number,
): Uint8ClampedArray

Gets a new Uint8ClampedArray view of the ArrayBuffer store for this array, referencing the elements at begin, inclusive, up to end, exclusive.

toLocaleString(): string

Converts a number to a string by using the current locale.

toString(): string

Returns a string representation of an array.

Returns the primitive value of the specified object.
