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.
