Or it might be the case that you just prefer to take other courses because they adapt better to your learning style.

set to 'on' or 'auto', and if you use a go.work file, set GOWORK=off.

Requirements may be added, updated, and removed with 'go get'.
The vendor directory may be updated with 'go mod vendor'.
A typical sequence might be:

    cd src  # or src/cmd
    go get golang.org/x/net@master
    go mod tidy
    go mod vendor

Use caution when passing '-u' to 'go get'. The '-u' flag updates

If you just don't know, use normal `def`.

**Note**: You can mix `def` and `async def` in your *path operation functions* as much as you need and define each one using the best option for you. FastAPI will do the right thing with them.

Anyway, in any of the cases above, FastAPI will still work asynchronously and be extremely fast.

But by following the steps above, it will be able to do some performance optimizations.

            val firStatement = firLeaf.statements[0]
            if (firStatement is FirExpression && firStatement.resolvedType == firLeaf.resolvedType) {
                // Trivial blocks might not appear in the CFG, so here we include their content
                return firStatement
            }
        }

        return firLeaf
    }

    You can actually skip that extra header and it would still work.

    But it's provided here to be compliant with the specifications.

    Also, there might be tools that expect and use it (now or in the future) and that might be useful for you or your users, now or in the future.

    That's the benefit of standards...

!!! tip
    It's possible that `ORJSONResponse` might be a faster alternative.

### `RedirectResponse`

Returns an HTTP redirect. Uses a 307 status code (Temporary Redirect) by default.

You can return a `RedirectResponse` directly:
