RecursiveCallList - Synchronous function queue caller until a valid value is returned (i.e., truthy or non-error)

recursiveCallList.js

// var _ = require('lodash');

var list = [
	function eenie () { throw new Error('hey'); },
	function meenie () { return 0; },
	function minie () { return false; },
	function moe () { return 'hello'; },
	function catcha () { return 'world'; }
];

// Recurse a list of functions, calling them in order until a valid value is returned
function recursiveCallList (list) {
	if (!isValid(list))
		return;
	return callFunc(_.first(list)) || recursiveCallList(_.tail(list));
}

// Validate input for the function list
function isValid (list) {
	return _.overEvery([
			_.isArray,
			_.negate(_.isEmpty),
			_.partial(_.every, _, _.isFunction)
		])(list);
}

// Call a function and return value (catching errors)
function callFunc (func) {
	var result = _.attempt(func);
	return !_.isError(result) && result;
}

console.log(recursiveCallList(list));
