Encounter Unspecified Variable Within app.get(...)

Express Enigma
After setting the variables
const username = "a"
const password = "a"
I attempted to reassign them using {username, password} = req.body (This was within a form on /createaccount)
However, I encountered an error message stating "unexpected token '='". Could this be due to 'username' not being defined in app.get(/createaccount...)???

Answer №1

Check out the code snippet below:

let user = "John";
let pass = "password123";

({user, pass} = req.body);

It is important to note that even though you have already declared 'user' and 'pass', when using destructuring in the next line, it is necessary to wrap the destructuring inside parentheses.

As mentioned on https://developer.mozilla.org/:

The parentheses ( ... ) around the assignment statement are required when using object literal destructuring assignment without a declaration.
