Get the byteLength
out of a DataView, robustly.
This will work in node <= 0.10 and < 0.11.4, where there's no prototype accessor, only a nonconfigurable own property.
It will also work in modern engines where DataView.prototype.byteLength
has been deleted after this module has loaded.
const dataViewByteLength = require('@teasource/nihil-molestiae-necessitatibus');
const assert = require('assert');
const ab = new ArrayBuffer(42);
const dv = new DataView(ab);
assert.equal(dataViewByteLength(dv), 42);
Simply clone the repo, npm install
, and run npm test
