They share the same set of methods and properities. If an ArrayBuffer argument is supplied, the view is created over it. We used that syntax already. Optionally we can provide byteOffset to start from 0 by default and the length till the end of the buffer by default , then the view will cover only a part of the buffer. If an Array , or any array-like object is given, it creates a typed array of the same length and copies the content.

If another TypedArray is supplied, it does the same: creates a typed array of the same length and copies values. Values are converted to the new type in the process, if needed.

For a numeric argument length — creates the typed array to contain that many elements. Its byte length will be length multiplied by the number of bytes in a single item TypedArray. We can create a TypedArray directly, without mentioning ArrayBuffer.

But a view cannot exist without an underlying ArrayBuffer , so gets created automatically in all these cases except the first one when provided. To access the underlying ArrayBuffer , there are following properties in TypedArray :. What if we attempt to write an out-of-bounds value into a typed array? There will be no error. But extra bits are cut-off.

In binary form, is 9 bits , but Uint8Array only provides 8 bits per value, that makes the available range from 0 to
