{{alias}}( obj, fcn[, thisArg] )
Invokes a function for each own enumerable property of an object.
When invoked, the function is provided three arguments:
- `value`: object property value
- `key`: object property
- `obj`: the input object
To terminate iteration before visiting all properties, the provided function
must explicitly return `false`.
The function determines the list of own enumerable properties *before*
invoking the provided function. Hence, any modifications made to the input
object *after* calling this function (such as adding and removing
properties) will *not* affect the list of visited properties.
Property iteration order is *not* guaranteed.
Parameters
----------
obj: Object
Input object, including arrays, typed arrays, and other collections.
fcn: Function
The function to invoke for each own enumerable property.
thisArg: any (optional)
Execution context.
Returns
-------
out: Object
Input object.
Examples
--------
> function logger( v, k ) { console.log( '%s: %d', k, v ); };
> var obj = { 'a': 1, 'b': 2, 'c': 3, 'd': 4 };
> {{alias}}( obj, logger )
a: 1
b: 2
c: 3
d: 4
