objectDiff
Usage
objectDiff will get the extra and different properties of the first object
ex.
objectDiff(
{
steel: {
sword: {
weight: 20
}
}
},
{
steel: {
train: {
contains: "coal"
}
}
});
yields
{
steel: {
sword: {
weight: 20
}
}
}
because all the stuff in a is not in b (this diff shows extra or different, only for the first object). You can get the same for the second object by reversing the order in your call
if two objects are are the same, objectDiff yields undefined
ex.
objectDiff({}, {}) === undefined //true
more examples.
objectDiff(
{
steel: {
sword:{
weight: 10
},
train: {
hasCoal: true
}
}
},
{
steel: {
sword: {
weight: 10
}
}
});
yields
{
steel: {
train: {
hasCoal: true
}
}
}
because the first object is only different in the path steel.train.hasCoal
