Lodash - forOwn method

Syntax

_.forOwn(object, [iteratee=_.identity])

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.

Arguments

• object (Object) − The object to iterate over.

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

Output

• (Object) − Returns object.

Example

var _ = require('lodash');
 
function Foo() {
   this.a = 1;
   this.b = 2;
}
 
Foo.prototype.c = 3;
 
_.forOwn(new Foo, function(value, key) {
   console.log(key);
});
