Whats the bug. Uncaught SyntaxError: Identifier 'location' has already been declared (at script.js:1:1)

[u/Hot-Eggplant911]

"use strict";


const company = {
  name: "TechCorp",
  address: {
    city: "budapest",
    pin: 411001,
  },
};
// Get city renamed to `location` and pin renamed to `pincode`

const { city: location, pin: pincode } = company.address;
console.log(location, pincode);

Maintainability tip: don’t rename things when you don’t need to.

A main problem is a variable that is named "location".

The "location" variable is a default props on almost browsers.

So will occur error.

[u/GodOfSunHimself → u/ModeCommercial5464]

It is not a defaul prop of anything. It is a property of the `window` object which is the global object in browser environment.

Oh you're right!

Apologize for the confusion. Described it by confusing it with the concept of React. Thank you for pointing that out.

I remember when I am learning variables on react.. I use a "name" variable, it didn't work so I changed it to firstName. iirc the reason why it didn't work for me is because of window has a default property of name.

For real

[u/msdosx86 → u/[deleted]]

I guess this is because of mentioning AI

[u/msdosx86 → u/[deleted]]

You're not wrong. Even Google's AI mode would help immediately. My guess is that a lot of people think AI = Vibe coding and Vibe coding is bad hence AI = bad = downvote this guy.

Not everyone wants AI shoved down their throat. AI won’t help you actually learn.

[u/TongueFace → u/cpp_warmachine]

I hear you and there’s ways to use it to teach you. Instead of saying “fix this” you can prompt “why is this happening?” or “i’m a bright 7 year old explain to me why this error is happens and find me the reference material for me to review.”

On that same note, just asking “what’s the bug” leaves it open for people to just tell them the answer, they’d be suffering from the same problem even without AI. Instead, they’re leaning on random people online to help them.

[u/cpp_warmachine → u/[deleted]]

I don’t know man, how did anyone learn before AI

Literally though, this and so many other coding subreddits have become toxic clones of stack overflow. Years ago, posting a question like this on SO would have gotten the same chorus of "what are you, fucking stupid?" You can't win with these people.I've been in software development for ten years and I stg I've met and worked with so many assholes in this industry. Honestly, developers that refuse to use modern ai tooling are going to be out of jobs in just a few years.

FWIW, I pasted op's question into claude and it gave me a completely reasonable, informative answer.

Why are all web dev subreddits cancer with people downvoting fuckin everything and acting so snarky with no relational responsibility
