Description
SharedArrayBuffer instances inherit from SharedArrayBuffer.prototype. As with all constructors, you can change the constructor’s prototype object to make changes to all SharedArrayBuffer instances.
Properties
SharedArrayBuffer.prototype.constructor
Specifies the function that creates an object’s prototype. The initial value is the standard built-in SharedArrayBuffer constructor.
SharedArrayBuffer.prototype.byteLength 只读
The size, in bytes, of the array. This is established when the array is constructed and cannot be changed. Read only.
Methods
SharedArrayBuffer.prototype.slice(begin, end)
Returns a new SharedArrayBuffer whose contents are a copy of this SharedArrayBuffer’s bytes from begin, inclusive, up to end, exclusive. If either begin or end is negative, it refers to an index from the end of the array, as opposed to from the beginning.
