• [predicate=_.identity] (Function) − The function invoked per iteration.

• [fromIndex=0] (number) − The index to search from.

Output

• (*) − Returns the matched element, else undefined.

Example

 var _ = require('lodash'); var list = [ { 'user': 'Joe', 'age': 36, 'active': true }, { 'user': 'Jake', 'age': 40, 'active': false } ]; var result = _.find(list, function(user) { return user.active; }); console.log(result);
