I need to create an object like {Dogs: []} where "Dogs" is passed in as a variable. I need to add my new object to this.state.

Then, I need to add objects to the array I've created. The new objects are in the form

{Dogs: [{name: "Fido"}, {name: "Snoopy"}]}

In this stage, the strings "Fido", "Snoopy", will be passed in as variables, and "Dogs" is passed in as a variable as well.

The syntax is defying me...

`var myObj = {}; myObj["Dogs"] = [ ... ];` – Matteo Tassinari Sep 22 '17 at 09:33

@MatteoTassinari: Or as of ES2015+: `var dogs = "Dogs"; var myObj = {[dogs]: [...]};` – T.J. Crowder Sep 22 '17 at 09:34
