Is there extension or function to know bracket declaration when focued close bracket

I want to know declaration of open bracket when focused close bracket.(ex. if (...) ).

I know emacs, vscode, vim are has goto declaration function. But, they needs 1 action(type M-.(emacs),F12(vscode),%(vim)). I don't want to type some key each time. So, I want to know declaration of bracket with 0-action.

I don't care how displays in declaration(pop-up, mini buffer, status bar)

Background: I'm in fixing legacy code. The code is too much nested with ifs and fors and whiles. By much nested, end of code are many continus close bracket(}) like below.

for (var item in list){
  if (cond1) {
    ...
    while( cond2 ) {
      ...
        if (cond3) {
            ...
        } else {
            ...
        }
      }
    }
    list.append(item)
  }
}

I usually mistake cond2 and cond3, created bugs, don't show log messages, and spent much time.

To quote Mass:

Yes- the plugin match-up has this feature: https://github.com/andymass/vim-matchup

enter image description here

enter image description here

Using the option 

let g:matchup_matchparen_offscreen = { 'method': 'popup' }

There is also the ability to show the match in the statusline (the default):

let g:matchup_matchparen_offscreen = { 'method': 'status' }`

When your cursor is on a bracket, the other one is highlighted automatically if you have :help matchparen enabled.

When your cursor is on a bracket, you can jump to the opening one with :help %.
