Local variable called 'name' conflicts with lib.d.ts 'name'

[minkir014]

I have a variable called name and it seems to be duplicated with a const in lib.dom.d.ts and this affects some functions in vs code like hovering and going to definition.
See this picture that shows the problem of hovering

and this shows the problem of going to definition when I press F12 It goes to this file

If you are not targeting the web, you can disable dom typings by setting "lib": ["es6"] in your jsconfig.json:

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es2016",
        "jsx": "preserve",
        "lib": ["es6"]
    },
    "exclude": [
        "node_modules",
        "**/node_modules/*"
    ]
}

Just for background, this is where it comes from: https://developer.mozilla.org/en-US/docs/Web/API/Window/name — meaning it's unavoidable and not a TS issue, since it is a global variable. EDIT: Okay, this should still be recognized as being overridden by a local variable in your code example. When I try that I have no issues though, "Jump to definition" takes me to the var statement and I get "var name: string" (I used a string in my test). I only get "const name: never" when I leave out the var, overriding the global "name".

@mjbvz That wasn't a typescript file. It was a javascript file. I published this issue to vs code as the compiler understand that but vs code doesn't. I am targeting web for your information.

[minkir014]

@lll000111 This is my code and that what I have. I don't understand how it worked for you. Tell me what's your steps.

[lll000111]

Tell me what's your steps.

@minkir014

I use WebStorm — but the TS language service. If that makes any difference it's not a TS issue anyway.

I added a var name = "something"; to a random TS file I had open in a TS project (that includes "dom" lib in tsconfig.json) and a console.log(name); statement. I queried the language server with CTRL-mouseover to see the inferred type(s). I removed var and checked again (plus I got a TS error now).

[minkir014]

@lll000111 Have you hovered over the name variable in the console.log(name); statement and gave you the same result? Plus, I think that it's a vs code problem. So, I opened an issue at vs code but it was transferred here.

[minkir014]

@lll000111 Are you here?

[lll000111]

@minkir014

Have you hovered over the name varia...

Yes.

Are you here?

I'm not sitting in front of a computer 24x7...

[minkir014]

@lll000111 Can you transfer this issue back to vs code issues?

[lll000111]

@minkir014 Me???

[minkir014]

If you can't. I'll close this issue and start another one with the same name.

TypeScript provides all the language services to VSCode, so it being here is appropriate.

See #18433 for further information about the issue.

[minkir014]

@kitsonk Are you using vs code. If so, try that and tell me what's your solution and if not, this issue repeated many times with vs code.
#18433
#31800
Although they are in typescript repository but they are also a problem with vs code.

[mjbvz]

I don't know why this was closed. @minkir014 We explained why this is happening and are keeping this open to see if the experience can be improved

[minkir014]

but it's strange that it works in webstorm and also the compiler understands that.

[RyanCavanaugh]

This is the intended behavior - without any other clues to the contrary, we assume you're editing a script file in a browser context.

[minkir014]

My project was targeting web with HTML, CSS and JavaScript and that works perfectly in web storm and also the browser evaluates that right. So, I think it must be a problem with vs code. So, reopen this issue,please.

[minkir014]

I think it's the same problem as #31800 and as what's said there the root problem is what my issue is talking about. So, reopen this issue and thank you.

[RyanCavanaugh]

This is the intended behavior and we don't intend to change anything here. Issues that don't have concrete next steps are closed, so that's the state this one will remain in unless there is evidence to suggest concrete next steps that should be done from our side.

[minkir014]

I am not who will tell you what will you do.. I am reporting a bug. This is not a PR.
