 This is a string that has 3 parts separated by a dot (.) and `base64` encoded. It can be decoded easily using any `base64` decoder.
 
 ```js
-const token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWUsImlhdCI6MTYzMjk0MTc4NCwiZXhwIjoxNjMyOTQ1Mzg0fQ.MVnMhRVLYhaGqtZEX4AiEMrQwFWRvRLp6MATodg6E6A';

 The first part defines the _algorithm_ and the type. The second part is called the payload or _claims_, which identifies the user, issue time, expiry time, and other data. The third part is called the _signature_.
