![]() In your second example youre ranging over the map and getting the key stored in k which only contains 1 and 2. The value being stored in k is the current index 0, 1, 2. To learn more about it, head over to the introduction on jwt.io before we dive straight into it. 1 Answer Sorted by: 0 Youre expecting range to behave the same on both types but in the first case its ranging over an array and you just have an empty index 0. JSON Web Tokens (JWT) have an inherent advantage over other methods, like Basic Authentication, by working as a token system instead of sending the username and password with every request. ![]() There are of course many different ways to build authentication into APIs these days - JSON web tokens being just one of them. In our example, we’re using a package called sentiment - which was trained against IMDB comment data - to judge whether our example sentences are positive or negative. If you sort the const group any other way, you introduce side effects. const ( Guest iota Member Moderator Admin ) Full source: /ThreeDotsLabs/go-web-app-antipatterns/02-enums/01-iota/role/role.go While Go is explicit, iota seems relatively obscure. It’s often used against datasets like tweets as it allows you to summarize a mass of small sentences into an easy to understand stat. iota Go lets you enumerate things with iota. ![]() Sentiment analysis is an interesting technique of judging whether a sentence, word or paragraph is considered a positive or negative thing. If they aren’t, you’ll receive the compile- time error which essentially means Go cannot read the syntax of your code (you didn’t write your code correctly). As you may already know, identifiers-user-defined program components, e.g., name of a function, variable, or package-in Go must be preceded by an underscore or a letter (a-z or A-Z). In the Go world, an underscore (_) before an expression is called a blank identifier. Struct Tags with Underscore Before Function Names
