Alternative to variable keys in Meteor

Question

How can I use a variable value as an object key?

For example, when adding an object dynamically to a Collection. When I to do it like this:

addToDB(type, account) {
  Accounts.insert({type: account});
};

it doesn't work as the key can't be a variable here.

for instance? can you give an example of what you trying to achieve — V31, Sep 11 '14 at 09:29

JavaScript object literal don't support dynamic keys.

Instead you can achieve the goal using :

var obj = {};
var key = "some key";
obj[key] = "test";

In your case:

addToDB(type, account) {
  var obj = {};
  obj[type] = account;
  Accounts.insert(obj);
};

Your answer is not accurate anymore. ES6 adds support for creating dynamic object keys. In case of the question above the answer would be `addToDB(type, account) { Accounts.insert({[type]: account}); };` Maybe you could improve your answer? – PaulT Jan 31 '17 at 20:25
