{{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.
|
||
|
|
|
||
|
|
