How can I turn a Javascript array of values into an array of Javascript objects by adding the same key for each? [duplicate]

Question

I want to turn something like this:

a = ['London', 'Brighton', 'Newcastle']

into something like this:

b = [{CityName: 'London'},{CityName: 'Brighton'},{CityName: 'Newcastle'}]

Any help would be much appreciated!

@HassanImam - you should capitalize CityName and write as an answer so I can upvote you :-) — Randy Casburn

You can use array#map to create an array of object.

a.map(CityName => ({CityName}))

const arr = ['London', 'Brighton', 'Newcastle'],
      result = arr.map(CityName => ({CityName}));
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
