The toHex()
method of Uint8Array
instances returns a hex-encoded string based on the data in this Uint8Array
object.
This method creates strings from a byte array. To convert individual numbers into hex, use the Number.prototype.toString()
method with radix
set to 16
instead.
None.
Return valueA hex-encoded string representing the data in the Uint8Array
.
This example encodes data from a Uint8Array
into a hex string.
const uint8Array = new Uint8Array([202, 254, 208, 13]);
console.log(uint8Array.toHex()); // "cafed00d"
const data = new Uint8Array([255, 0, 0, 0, 255, 0, 0, 0, 255]);
for (let i = 0; i < data.length; i += 3) {
console.log(data.slice(i, i + 3).toHex());
}
// "ff0000"
// "00ff00"
// "00ff00"
