javascript - How to delete key-value pair from an object?





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



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