So, the binary data in an ArrayBuffer of 16 bytes can be interpreted as 16 “tiny numbers”, or 8 bigger numbers (2 bytes each), or 4 even bigger (4 bytes each), or 2 floating-point values with high precision (8 bytes each). Sending and Receiving Binary Data. This example reads an image as a binary file and creates an 8-bit unsigned integer array from the raw bytes. Note that this will not decode the image and read the pixels. This is building a 512-byte array of 8-bit integers and sending it; you can use any binary data you'd like, of course.

The ArrayBuffer object is used to represent a generic, fixed-length raw binary data buffer.. It is an array of bytes, often referred to in other languages as a "byte array". You cannot directly manipulate the contents of an ArrayBuffer; instead, you create one of the typed array objects or a DataView object which represents the buffer in a specific format, and use that to read and write the A File object in JavaScript references an actual file in the local filesystem. This File object inherits all properties and methods from the Blob class. Although the File objects and Blob objects are different, they expose same methods and properties.
