JSHint doesn't work in vim

Question

On invoking :SyntasticInfo:

Syntastic version: 3.8.0-94 (Vim 800, Linux, GUI)
Info for filetype: javascript
Global mode: active
Filetype javascript is active
The current file will be checked automatically
Available checker: jshint
Currently enabled checker: jshint

I've installed both JSHint and Syntastic via vim-pathogen.

What is one supposed to configure in order to make the syntax checking work?

In Syntastic's documentation on JSHint, nothing special is mentioned about configuration, other than

This checker is initialised using the "makeprgBuild()" function and thus it accepts the standard options described at |syntastic-config-makeprg|.

On a side note, syntax checking does work for TypeScript, using Syntastic.

Show us your .vimrc, particularly as is relates to your Syntastic settings. — Christian Gibbons
So, what did you do, what did you expect to happen, and what happened instead? How did you conclude it doesn't work? — lcd047
@lcd047 For instance, for the purpose of checking its functionality, I omitted a closing bracket in a function definition. This doesn't trigger an error by Syntastic. The same for other forms of incorrect syntax. — Mussé Redi
Does the same file trigger an error when you run jshint against it with the same options as syntastic? Syntastic itself doesn't care about JavaScript syntax, you know. — lcd047

You don't have any configuration for Syntastic telling it to run. You might start with the recommended settings as listed when you run :help syntastic-recommended:

set statusline+=%#warningmsg#
set statusline+=%{SyntasticStatuslineFlag()}
set statusline+=%*

let g:syntastic_always_populate_loc_list = 1
let g:syntastic_auto_loc_list = 1
let g:syntastic_check_on_open = 1
let g:syntastic_check_on_wq = 0

You can also manually invoke Syntastic with :SyntasticCheck

If it is on-the-fly linting that you desire, as recommended in one of the comments, then you should switch from Syntastic to ALE (I recommend ALE in general)
