"Scanning tags" with javascript takes time

[ghost]

I've got froze a little bit and difficulty when try to use completor with javascript, I followed https://github.com/ternjs/tern_for_vim#manual and https://github.com/maralla/completor.vim#javascript status bar show "scanning tags" when trigger completor.vim.

gvim 1-1802/windows 10, all lastest plugins include completor.vim

produce steps:

choco install nodejs

in plugins\start\tern_for_vim:

npm install

vi .vimrc

let g:completor_node_binary = 'C:\Program Files\nodejs'

Thanks.
