How can I use a variable as the name parameter in an object?

Question

How can I use a variable as the name parameter in an object?

var field = 'profile.email'

var value = 'example@email.com'

var query = { field : value };

console.log(query);

Current output:

{ field : 'example@email.com' }

Output I want to achieve:

{ 'profile.email' : 'example@email.com' }

FWIW, the correct terminology is "property name", not "parameter". — Felix Kling, Apr 24 '17 at 20:06

You can e.g. drop the field variable inside square brackets.

var field = 'profile.email',
    value = 'example@email.com',
    query = { [field] : value };

    console.log(query);
