The opposite of `mapValues` this method creates an object with the same values as `object` and keys generated by running each own enumerable string keyed property of `object` thru `iteratee`. The iteratee is invoked with three arguments: (value, key, object).
mapKeys({ 'a': 1, 'b': 2 }, function(value, key) {
return key + value
})
// => { 'a1': 1, 'b2': 2 }
Name | Type | Attribute | Description |
---|---|---|---|
object | The object to iterate over. | ||
iteratee | The function invoked per iteration. |
