Lodash

forOwn

Object
since 0.3.0

Arguments

  • Object The object to iterate over.
  • Function The function invoked per iteration.

Returns

Object `object`.

Iterates over own enumerable string keyed properties of an object and invokes iteratee for each property. The iteratee is invoked with three arguments: (value, key, object). Iteratee functions may exit iteration early by explicitly returning false.

Example of Lodash _.forOwn

function Foo() {
  this.a = 1;
  this.b = 2;
}

Foo.prototype.c = 3;

_.forOwn(new Foo, function(value, key) {
  console.log(key);
});
// => Logs 'a' then 'b' (iteration order is not guaranteed).
