Function createDataView

Create a DataView from a Uint8Array. This is a convenience function that avoids having to create a DataView manually, which requires passing the byteOffset and byteLength parameters every time.

Not passing the byteOffset and byteLength parameters can result in unexpected behavior when the Uint8Array is a view of a larger ArrayBuffer, e.g., when using Uint8Array.subarray.

This function also supports Node.js Buffers.

Example

const bytes = new Uint8Array([1, 2, 3]);

// This is equivalent to:
// const dataView = new DataView(bytes.buffer, bytes.byteOffset, bytes.byteLength);
const dataView = createDataView(bytes);

Returns

The DataView.
