Uint8ClampedArray

The Uint8ClampedArray typed array represents an array of 8-bit unsigned integers clamped to 0-255; if you specified a value that is out of the range of [0,255], 0 or 255 will be set instead; if you specify a non-integer, the nearest integer will be set. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

Static Members #

Returns a number value of the element size. 1 in the case of an Uint8ClampedArray.

Creates a new Uint8ClampedArray with a variable number of arguments. See also Array.of().

Instance Members #

Returns a number value of the element size.

Returns the ArrayBuffer referenced by the Uint8ClampedArray Fixed at construction time and thus read only.

Returns the length (in bytes) of the Uint8ClampedArray from the start of its ArrayBuffer. Fixed at construction time and thus read only.

Returns the offset (in bytes) of the Uint8ClampedArray from the start of its ArrayBuffer. Fixed at construction time and thus read only.

Returns the number of elements hold in the Uint8ClampedArray. Fixed at construction time and thus read only.

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

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

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

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

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().

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().

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().

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

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

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().

Joins all elements of an array into a string. See also Array.prototype.join().

Returns a new Array Iterator that contains the keys for each index in the array. See also Array.prototype.keys().

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

Creates a new array with the results of calling a provided function on every element in this array. See also Array.prototype.map().

Apply a function against an accumulator and each value of the array (from left-to-right) as to reduce it to a single value. See also Array.prototype.reduce().

Apply a function against an accumulator and each value of the array (from right-to-left) as to reduce it to a single value. See also Array.prototype.reduceRight().

Reverses the order of the elements of an array — the first becomes the last, and the last becomes the first. See also Array.prototype.reverse().

Stores multiple values in the typed array, reading input values from a specified array.

Extracts a section of an array and returns a new array. See also Array.prototype.slice().

Returns true if at least one element in this array satisfies the provided testing function. See also Array.prototype.some().

Sorts the elements of an array in place and returns the array. See also Array.prototype.sort().

Returns a new TypedArray from the given start and end element index.

Returns a new Array Iterator object that contains the values for each index in the array. See also Array.prototype.values().

Returns a string representing the array and its elements. See also Array.prototype.toString().

Returns a string representing the array and its elements. See also Array.prototype.toString().
