Module find

find

• find<T>(collection: ArrayLike<T>, predicate?: string, fromIndex?: number): T | undefined
• find<T>(collection: ArrayLike<T>, predicate?: ((item: T) => boolean), fromIndex?: number): T | undefined
• find<T>(collection: ArrayLike<T>, predicate?: Partial<T>, fromIndex?: number): T | undefined
• find<T>(collection: ArrayLike<T>, predicate?: any, fromIndex?: number): T | undefined

• Iterates over elements of collection, returning the first element predicate returns truthy for. The predicate is invoked with three arguments: (value, index|key, collection).

  example

  var users = [
    { 'user': 'barney',  'age': 36, 'active': true },
    { 'user': 'fred',    'age': 40, 'active': false },
    { 'user': 'pebbles', 'age': 1,  'active': true }
  ];
  
  find(users, function(o) { return o.age < 40; });
  // => object for 'barney'
  
  // The `matches` iteratee shorthand.
  find(users, { 'age': 1, 'active': true });
  // => object for 'pebbles'
  
  // The `matchesProperty` iteratee shorthand.
  find(users, ['active', false]);
  // => object for 'fred'
  
  // The `property` iteratee shorthand.
  find(users, 'active');
  // => object for 'barney'
