Why even use else if with return...

> Why even use else if with return...

What is the problem with that? How would you write that snippet? It is common in the new functional js landscape, even if it is pass-by-ref.

Using guard clauses. Way more readable and easy to work with.

  export function extractSearchToken(completionToken: {
    token: string;
    isQuoted?: boolean;
  }): string {
    if (completionToken.isQuoted) {
      return completionToken.token.slice(2).replace(/"$/, '');
    }
    if (completionToken.token.startsWith('@')) {
      return completionToken.token.substring(1);
    }
    return completionToken.token;
  }

I always write code like that. I don't like early returns. This approximates `if` statements being an expression that returns something.

Do you care to elaborate? "if (...) return ...;" looks closer to an expression for me:

  export function extractSearchToken(completionToken: { token: string; isQuoted?: boolean }): string {
    if (completionToken.isQuoted) return completionToken.token.slice(2).replace(/"$/, '');

    if (completionToken.token.startsWith('@')) return completionToken.token.substring(1);

    return completionToken.token;
  }

I’m not strongly opinionated, especially with such a short function, but in general early return makes it so you don’t need to keep the whole function body in your head to understand the logic. Often it saves you having to read the whole function body too.

But you can achieve a similar effect by keeping your functions small, in which case I think both styles are roughly equivalent.

I'm not that familiar with TypeScript/JavaScript - what would be a proper way of handling complex logic? Switch statements? Decision tables?

Here I think the logic is unnecessarily complex. isQuoted is doing work that is implicit in the token.

Fits with the origin story of Claude Code...

insert "AI is just if statements" meme

useCanUseTool.tsx looks special, maybe it'scodegen'ed or copy 'n pasted? `_c` as an import name, no comments, use of promises instead of async function. Or maybe it's just bad vibing...

Maybe, I do suspect _some_ parts are codegen or source map artifacts.

But if you take a look at the other file, for example `useTypeahead` you'd see, even if there are a few code-gen / source-map artifacts, you still see the core logic, and behavior, is just a big bowl of soup

Lol even the name is crazy
