Question 1

How to parse a TAR file with jBinary?

Accepted Answer

Define or use a TAR typeset, load the file with jBinary.load('file.tar', TAR), then read and modify data as JavaScript objects, as shown in the README example. This abstracts binary details into high-level operations.

Question 2

jBinary vs Node.js Buffer: which is better for binary data?

Accepted Answer

jBinary is ideal for complex, structured binary data with declarative types, simplifying code, while Node.js Buffer is better for low-level, performance-critical tasks. jBinary adds abstraction that may slow down simple operations.

Question 3

Can jBinary handle endianness in binary files?

Accepted Answer

Yes, jBinary supports endianness through its typeset definitions, allowing specification of byte order for data types, leveraging jDataView's underlying capabilities for cross-platform consistency.

Question 4

How to save modified binary data to a file in the browser?

Accepted Answer

After writing changes with methods like writeAll(), call jb.saveAs('filename') to trigger a download, as demonstrated in the TAR example. This uses browser APIs for file saving.

Question 5

Is jBinary good for real-time video streaming apps?

Accepted Answer

It can handle formats like MPEG-TS, as shown in the demo, but the high-level abstraction may introduce performance overhead, making it less suitable for latency-sensitive streaming compared to raw binary libraries.

Question 6

What browsers support jBinary?

Accepted Answer

jBinary works in modern browsers via jDataView polyfill, requiring support for Typed Arrays and Promises. It may have compatibility issues in older browsers without these features.
