    is-function

    browser support

    Is that thing a function? Use this module to find out.

    API

    module.exports = function isFunction(fn) -> Boolean

    Return true if fn is a function, otherwise false.

    Why not typeof fn === 'function'

    Because certain old browsers misreport the type of RegExp objects as functions.
