Sourcing multiple files?

[maasha]

If I have a function defined in one file that is used in another file I get warnings on defined but not used and not defined. What can be done?

If you're using a module loading system, like browserify's require() then this won't be an issue.

a.js

exports.foo = function () {}

b.js

var a = require('./a')
a.foo()

But it sounds like you're just including both a.js and b.js in a page via <script> tags.

a.js

function foo () {}

b.js

foo()

index.html

<script src="a.js"></script>
<script src="b.js"></script>

To make the relationship between these files, clear to the linter (and to readers of your code), you should explicitly reference where the foo() function is coming from in b.js.

b.js

window.foo()

That should fix your issue!

Great, thanks!

One note. The window.foo() explicit call does silence the warning in b.js but in a.js I still get a foo is defined but never used warning

[imjoehaines]

In a.js, if you assign your function to window.foo instead of just foo then the warning should go away

Yep, what @imjoehaines said.
