Elegant way to add property to each element in an array

Question

How can I using lodash, with minimum code transform an array like this:

['Alfa','Betta','Gamma','Delta']

into:

[
 { squad: 'Alfa'},
 { squad: 'Betta'},
 { squad: 'Gamma'},
 { squad: 'Delta'},
]

Answer 1

In Lo-Dash (or Underscore):

_.map(['Alpha', 'Beta', 'Gamma', 'Delta'], function (squad) {
    return { squad: squad };
});

In ES5:

['Alpha', 'Beta', 'Gamma', 'Delta'].map(function (squad) {
    return { squad: squad };
});

In ES2015:

['Alpha', 'Beta', 'Gamma', 'Delta'].map(squad => ({ squad }));
