JSLint: was used before it was defined

I run JSlint and saw errors like that:

'foo' is not defined.
var x = foo();

foo is a function defined in another JavaScript file foo.js. As I understand there is no "import / require" directives in JavaScript to reference the foo function defined in another source file.

How can I fix this error repoted by JSlint?

Use the global directive to tell JSLint about foo's assumed existence.

/*global foo */
