How to delete key-value pair from an object? [duplicate]

Question

I have a variable data that contains some key-value pairs like this:

var data = {
    "1": 127,
    "2": 236,
    "3": 348
}

router.delete('/values/:id', function(req, res, next){
    var id = req.params.id;

})

How can I delete the key-value pair that has a key equal to the id variable?

Answer 1

delete data[req.params.id] or delete data[id] should work.
