adding data to firebase realtime database from an object (web)
I have an object containing multiple key value pairs, I want to add all the keys and their values, from inside the object to an existing node, without disturbing the data already present inside the node.
If i write like this
var ref = firebase.database().ref("hams/spam_words/");
ref.update({
new_words_ham //new_word_ham is an object containing n number of words
});
it will add new_words_ham as another child node inside the main node , i cannot have that
even using a forloop on the object does not work
var ref = firebase.database().ref("hams/spam_words/");
for(var i in new_words_ham){
var word = i
ref.update({
i
});
I am new to js as well as to firebase. Please do tell me if i have got any concept wrong

This statement looks a bit strangeref.update({ new_words_ham });Are the wrapping curly brackets a typo or is removing them solving your problem?

@DennisAlund modern JavaScript allows{ new_words_ham }as a shorthand for{ new_words_ham: new_words_ham }. Yes, I find it incredibly hard to get used to too. ;-)

Your existing code
//new_word_ham is an object containing n number of words
firebase.database().ref("hams/spam_words/").update({
new_words_ham
});
Can be rewritten as
firebase.database().ref("hams/spam_words/").update({
new_words_ham: new_words_ham
});
when the shorthand syntax is expanded. What I believe you want is simply
firebase.database().ref("hams/spam_words/").update(new_words_ham);
