ReferenceError: DataView is not defined

[silverbasilisk]

Hello @PiotrDabkowski I tried with this js code but it's causing error.

// JavaScript
BinBuffer.allocate = function (uiLength) {
    uiLength = self.position + uiLength;
    if (self.buf != null && self.buf.length > uiLength) {
        return
    }
    var temp = new ArrayBuffer(Math.max(256, uiLength * 2));
    if (self.buf != null) {
        new Uint8Array(temp).set(new Uint8Array(self.buf));
        self.buf = undefined
    }
    self.buf = temp;
    self.vew = undefined;
    self.vew = new DataView(self.buf)
};

// error
