How do I make an ArrayBuffer immutable in Javascript?

Question

How do I make the content of an ArrayBuffer immutable in Javascript? The Object.freeze() method does not seem to be working. Is there any method to achieve it? Would it be even possible?

Answer 1

You can convert the ArrayBuffer to an immutable string as a data URI defined using const

const reader = new FileReader;

reader.onload = () => { const ab = reader.result // `ab` cannot be changed }

reader.readAsDataURL(new ArrayBuffer(123));
