Uint8Array.fromBase64()

The Uint8Array.fromBase64() static method creates a new Uint8Array object from a base64-encoded string.

This method should be preferred over Window.atob() because it results in a byte array, which is easier to work with than a string containing raw bytes, unless your decoded binary data is actually intended to be ASCII text. If you already have an array buffer allocated and you want to populate it, use the instance method Uint8Array.prototype.setFromBase64() instead.

Return value: A new Uint8Array object containing the decoded bytes from the base64-encoded string.

Syntax example: Uint8Array.fromBase64(string)
