Using SHA-256 with NodeJS Crypto

I’m trying to hash a variable in NodeJS like so:

var crypto = require('crypto');
var hash = crypto.createHash('sha256');
var code="bacon";
code = hash.update(code);
code = hash.digest(code);
console.log(code);

But looks like I have misunderstood the docs as the console.log doesn’t log a hashed version of bacon but just some information about SlowBuffer.

What’s the correct way to do this?

base64:

const hash = crypto.createHash('sha256').update(pwd).digest('base64');

hex:

crypto.createHash('sha256').update(pwd).digest('hex');
