To Reproduce

Steps to reproduce the behavior:

1. Start vim, nvim -u min-vimrc.vim ...
2. insert content

function abc(b) {
}

3. type abc, check candidates list, two options provided by LC and nvim-typescript is different (check screenshot)

Current behavior

function missing arguments and return info provided by language-client

Expected behavior

function should have arguments and return info provided by language-client

Is this configuration related or does javascript-typescript-langserver not support it?

I also never could make this work -- I switched many different typescript language servers and none of them worked. It seems that all of the them provides these typings, but for some unknown reason LanguageClient-neovim isn't working with them. I can get typings on Elixir language server, though.

I'm also having this issue. Only happens with the typescript language server

I've migrated to https://github.com/neoclide/coc.nvim and now I have the most awesome setup I ever had.
