To get the sha1 hash of a string in Node.js, we can use the crypto module.

For instance, we write

const crypto = require("crypto");
const shasum = crypto.createHash("sha1");
shasum.update("foo");
const digest = shasum.digest("hex");

to call crypto.createHash to create the shasum hash object.

Then we call shasum.update to update the hash with the 'foo' string.

And then we return the hash digest with digest.
