var _ = require('underscore');

var list = [1, 2, 3, 4, 5, 6]
//Example 1. find first even number
var result = _.find(list, function(num) { return num % 2 == 0 });
console.log(result);

//Example 2. find first odd number
var result = _.find(list, function(num) { return !(num % 2 == 0) });
console.log(result);
